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 DOT 5.1 fluid
to each piston, then install each piston into each piston bore.
NOTICE
For the best braking performance, use only SRAM DOT 5.1 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.
Use a pick to remove the caliper o-ring from the inboard caliper half
and install a new o-ring.
