2008 Cadillac STS Brake Caliper

The procedure is to remove the brake caliper from the brake caliper bracket and support the brake caliper with heavy mechanic's wire, or equivalent, remove the brake pads from the brake caliper bracket, remove the brake pad retainers from the brake caliper bracket, remove the brake caliper bracket bolts, remove the rear brake caliper bracket, install the brake caliper, replace the brake caliper bracket if cracked or damaged.

The procedure is to install the brake caliper bleeder valve, install the brake caliper bleeder valve cap, lubricate the new piston seal with Delco Supreme 11(R), GM P/N 12377967 (Canadian P/N 992667) or equivalent DOT-3 brake fluid, install the new lubricated piston seal into the caliper bore seal groove, lubricate the brake caliper bore and the piston with brake fluid, install the caliper piston into the caliper bore, install the new piston dust boot seal over the piston, assemble the J 8092 and the J 46275, and install the caliper to the vehicle.

The recommended torque is 130 N.m (96 lb-ft).

The procedure is to inspect the fluid level in the brake master cylinder reservoir, raise and support the vehicle, remove brake fluid to the midway point before proceeding if the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove the tire and wheel assembly, insert a plastic flat-bladed trim tool between the rotor and inboard brake pad, apply pressure to the inboard brake pad until both caliper inner pistons are compressed into the caliper piston bores, insert a plastic flat-bladed trim tool between the rotor and outboard brake pad, apply pressure to the outboard brake pad until both caliper outer pistons are compressed into the bores, remove the brake hose to caliper bolt attaching the brake hose to the brake caliper, remove the brake hose from the brake caliper, remove and discard the 2 copper brake hose gaskets, plug the opening in the brake caliper and the brake hose to prevent fluid loss and contamination, remove the brake caliper bolts, remove the brake caliper.

You should not place your fingers in front of the piston to catch or protect the piston while applying compressed air. This could result in serious injury.
