Why we use DOT4
DOT4
•
•
•
•
•
Low level of compressibility  stable performance / Lever feel.
Constant viscosity  consistent lever feel.
Higher dry and wet boiling point than mineral oil  fade resistant.
Less hygroscopic than DOT 5.1  Requires less bleeding/service.
Recommended bleed of the system every 6 to 12 months.
Recommended fluids for brake service
•
•
•
•
Use DOT4 Brake fluid only!
High percent Isopropyl alcohol for cleaning the system and the discs.
Brake cleaner only for cleaning and mobilizing the caliper pistons.
Silicone grease for seals and parts. NO TEFLON BASED GREASE.

Requirements for proper function
First engagement of caliper pistons
•
•
When brand new or after long periods non-actuation, caliper pistons can stick to
the quadrings limiting their free movement. To free the pistons, pull the brake
lever several times and then reset them by pushing them back into caliper body.
Adjust pistons with included spacer.
Checking the lever stroke
•
The lever stroke of Formula Brakes is around 20mm. The cause of an excessively
short stroke is most frequently excessive fluid in the system caused by expansion.
Even when not in use, the hydroscopic nature of DOT fluid causes it to expand over
time and the system will need to be equalized by burping out excess fluid before
the correct amount of free-stroke is realized.

Requirements for proper function
Mounting points
•
•
•
•
Frame and Fork mounting points must be properly aligned, faced and free of paint.
Always use medium strength thread-locker for mounting fasteners.
Always use washers under bolt heads for caliper mounting.
Always torque all fasteners to spec.
Cleaning
•
Rotors must be free of grease or oils for proper function. Before the initial use,
clean the rotors with a high % isopropyl alcohol on a clean rag.

Troubleshooting
Caliper pistons don‘t reset all the way
1.
2.
3.
4.
Excess fluid in the system.
Dry and/or heavily dirty caliper pistons.
Friction at quadrings is too low.
Caliper oxidation.
Inconsistent lever contact point
1.
2.
3.
4.
5.
6.
Air in the system
Dry and/or heavily dirty caliper pistons.
Friction at quadrings is too high.
Caliper oxidation.
Leaking membrane.
Pump piston damage.

Troubleshooting
Lever blade does not fully return
1.
2.
3.
Seals experienced expansion after exposure to non-approved oil or grease
(WD40, Triflow etc.).
Lever pivot contaminated.
Lever blade fixing screws over-torqued causing binding.
Rotor rub
1.
2.
3.
4.
Check caliper pistons to ensure proper movement and retraction.
Check rotors trueness.
Check to ensure wheel is fully seated in dropouts.
Check mounting points of Caliper, adapter and rotor for correct alignment.

7.
8.
Contaminated pads/rotor.
Caliper pistons retraction limited.
Pads not properly bedded in.
Bent pad spring contacting rotor when pistons actuating.
Rotors overheated and glazed (brake track is black/discolored).
Frequency vibration on frame, wheels or fork.
Pad type not appropriate for riding style.
Wet conditions.
