Assembly Procedure

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: 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 GM approved brake fluid from a clean, sealed brake fluid container to the piston, piston seal, and piston bore.
