Damage to the pistons (phenolic)
14. Clean the brake caliper assembly with denatured alcohol.
15. Dry with filtered, lubricated compressed air.
Assembly Procedure
1. Important: When applying the clean brake fluid to the piston bores and pistons, only apply the brake fluid to one bore at a time. This is done to
ensure that the brake caliper, seals and pistons DO NOT become contaminated with dirt or other foreign material.
Apply a small amount of clean DOT-3 brake fluid to the piston, piston seal, and piston bore.
2. Install the piston seal in the brake caliper.
3. Install the dust seal on the piston.
