Caliper Bracket

When replacing the front Brake Caliper Bracket start by maintaining the brake caliper position with heavy mechanic wire or an equivalent support system that keeps the hydraulic flexible brake hose connected to prevent damage and brake fluid leaks. Start by taking off the front brake pads before accessing the caliper bracket bolts then properly remove the caliper bracket . Begin by cleaning all threads on caliper bracket bolts before checking the mounting hole condition of the knuckle for optimal clamp strength. Brake Caliper Bracket bolts require threadlocker gm p/n 12345493 (Canadian P/N 10953488) for thread application. Using the bracket bolts install the caliper bracket while torquing them to 180 nm (133 lb ft). Place the front brake pads and caliper unit as the last step.

Remove the caliper bracket bolts and then the caliper bracket.

Remove the brake caliper bracket bolts and the rear brake caliper bracket itself.

180 Nm (133 ft. lbs.).

Remove the rear brake pads, followed by the caliper bracket bolts, and then take off the caliper bracket.

Secure the caliper bracket using the bracket bolts, tightening them to 185 Nm (137 ft. lbs.).

Remove the caliper from the mounting bracket without disconnecting the hydraulic brake flexible hose.

Detach them from the bracket, inspect the bracket for any cracks, and replace it if necessary.

Reinstall the front brake pads and the caliper.

Clean and inspect the threads of the caliper bracket bolts and the mounting holes in the knuckle to ensure proper clamp load.

Apply THREADLOCKER, GM P/N 12345493 (Canadian P/N 10953488) to the threads of the caliper bracket bolts.

Support the brake caliper with heavy mechanics wire or an equivalent tool after removing it from the mounting bracket, ensuring the hydraulic flexible brake hose remains connected.
