New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

monitoring sensors, High performance brake liner, etc.
Brake Actuation system is 9 bar with oil separator and 230 CC compressor for in un interrupted
supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

monitoring sensors, High performance brake liner, etc.
Brake Actuation system is 9 bar with oil separator and 230 CC compressor for in un interrupted
supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New Generation Technology Brakes
Definition:
•
•
NGT is recent updated version of CGT Brake in which ;
Foundation brake is better in Lining life, reduced Brake Noise, provision of Wear and temperature
monitoring sensors, High performance brake liner, etc.
Brake Actuation system is 9 bar with oil separator and 230 CC compressor for in un interrupted
supply of clean air.
New features
Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

Lining Wear Sensor for Foundation brake
Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal
to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is
worn out and due for replacement.
Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

Advantages of using Wear Sensor:
•
•
•
Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to
complete lining wear.
Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.

New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness
in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
•
•
•
•
Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in
uniform torque. (Less Noise)
In the Transfer Film Technology friction is produced by inter action of films rather than
mechanical action between drum and lining which produces vibration. Therefore the reduction on
brake Noise.
This also reduces thermal effect on foundation brake and thus improves lining life. (Almost
Double).
Constant deceleration and stopping distance even when vehicle reaches to High speed up to
100kmh.
