Caliper Bracket, Front

To replace the front Brake Caliper Bracket (without J55), support the brake caliper with heavy mechanic's wire after removing it from the mounting bracket in such a way that the hydraulic brake flexible hose stays attached, to avoid causing damage to its ends. Next, unscrew the brake pads and Brake Pad retainers from the Brake Caliper Bracket , Brake Caliper Bracket bolts , and then remove the bracket itself. Clean any dirt or rust from the Brake Caliper Bracket and do a rational check on it for cracks and damages and replace it if that is found to be necessary. Thorough the bolt threads and the threaded holes with denatured alcohol or equivalent (if needed) prior to installation allowing them to dry. Apply threadlocker gm p/n 12345493 (Canadian P/N 10953488) to two thirds of the length of the threaded area of the lower caliper bracket bolts so that there are no gaps and let it cure for roughly ten minutes before proceeding. Place the Brake Caliper Bracket onto the Steering Knuckle, then fasten and tighten the Brake Caliper Bracket bolts, to 185 nm (137 ft. Lbs). Spray a thin layer of niglube at the brake calper pin bits then fit the Brake Pad retainer in place with brake pads to the brake calper bracket and then fit the brake calper.

Reinstall the caliper mounting bracket and the brake caliper using the appropriate replacement procedure for the front or rear, with or without J55.

Install the brake pad retainers and brake pads to the brake caliper bracket before finally installing the brake caliper.

A small amount of LOCTITE(R) DRI-LOC 201 (GM P/N 12345493) or equivalent.

Next, take out the brake pads and the brake pad retainers from the brake caliper bracket.

Ensure that the threads of the brake caliper bracket bolts and the threaded holes are free of residue and debris by cleaning them with denatured alcohol or an equivalent and allowing them to dry.

Apply a thin coat of high-temperature silicone lube to the brake caliper pin bolts.

Remove the brake caliper from the mounting bracket, then take out the brake pads and brake pad retainers from the brake caliper bracket.

Remove the brake pads and brake pad retainers from the brake caliper bracket, followed by the brake caliper bracket bolts and the bracket itself.

Ensure to support the brake caliper with heavy mechanic's wire or an equivalent while keeping the hydraulic brake flexible hose connected.

Lubricate the brake caliper pin bolts with a thin coat of high-temperature silicone lube.

Apply threadlocker GM P/N 12345493 (Canadian P/N 10953488) to two-thirds of the threaded length, ensuring no gaps, and allow it to cure for approximately ten minutes.

Remove the two caliper bracket bolts and take off the caliper bracket.

Lubricate them with silicone grease.
