10.10 Disc Brakes

Cleaning
Under normal use and conditions, it is not necessary to clean the caliper rotor or pads. If necessary, use a solution of water and dish detergent to
wash the caliper and rotor. Thoroughly rinse all soap residue from the rotor. Dry the components completely with a clean paper towel.
Cable Adjustment
Use the barrel adjuster to remove cable slack. Turn the barrel adjuster
until there is no free play in the brake lever but not so far that the torque
arm on the caliper is advanced.
 The torque arm should return completely when the brake
lever is released.
Spring Adjustment
To adjust spring tension, turn the spring tension adjustment screw with
a 2 mm hex wrench. Turn the screw clockwise to increase the spring
tension, which equals harder lever pull.
Brake Pad Inspection, Replacement and Break In
 A brake pad MUST be replaced when its thickness (backing
plate and friction material) is less than 3 mm.
If the rotor is damaged or excessive wear is found,
replacement should be done by a qualified technician.
Inspect the brake pad for thickness and wear. To replace brake pad:
1. Remove the existing pad.
A. Back both adjuster knobs all the way out (counterclockwise).
B. Squeeze the pad tabs together and pull both pads straight out
of the caliper.
2. Install replacement pad and springs.
A. Assemble the spring between the new left and right pads.
The pad marked "R" goes on the spoke side of the brake.
B. Align the spring to the pad as shown.
C. Squeeze the brake pad and spring clip assembly together then
press firmly into the caliper until it clicks into place.
