Assembly Procedure
Important: When applying the clean brake fluid to the piston bores, piston seals and pistons, only apply the brake fluid to one bore at a
time. This is done to ensure the brake caliper, seals and pistons DO NOT become contaminated with dirt or other foreign material.
1. Apply a small amount of clean DOT-3 brake fluid to the piston, piston seal, and piston bore.
