12Caliper Piston Installation
Caliper Piston Installation
NOTICE
DOT fluid will damage painted surfaces. If any fluid comes in contact with a painted surface (i.e. your frame) or printing on the brakes, wipe it off
immediately and clean it with isopropyl alcohol or water. Damage to painted and/or printed surfaces by DOT fluid is not covered under warranty.
Inspect the caliper pistons for damage and replace the pistons if
necessary.
Use your gloved finger to apply a small amount of SRAM®
High-Performance 5.1 DOT fluid to the circumference of each piston.
Install the pistons into each half of the caliper body.
NOTICE
For the best braking performance, use only SRAM
High-Performance 5.1 DOT fluid. If SRAM fluid is not available, use only
DOT 5.1 or 4 fluid. Do not use grease. Grease will prevent the pistons
from fully retracting into the caliper bores which will reduce braking
performance.
Spray isopropyl alcohol on the caliper halves and both of your gloves,
and clean them with a shop towel.
Install new caliper o-rings onto the outboard caliper half.
Add a small amount of DOT compatible grease onto the installed
o-rings to help them stay in place, or to prevent them from falling out,
as you assemble the caliper.
