Check the brake master cylinder fluid before replacing the front Brake Caliper Bracket on 1500 series by draining excess fluid to the midway point between markings. Hook two c-clamps onto the caliper housing to push back its pistons until they extend fully while pressing them against the rear of the outboard pad. Once you rid yourself of the c-clamps you must uninstall the brake caliper bolts while keeping the brake components detached so footage on the brake pedals will not harm anything. Secure the caliper with mechanic's wire and let the hydraulic brake hose stay connected before removing
Brake Pads and clips. After that, take out the Brake Caliper Bracket bolts to take off the whole bracket assembly. Wipe all debris from the surfaces and holes on the bracket before starting installation. Use new Brake Caliper Bracket while removing old adhesive from its mounting surface and treating bolt threads with denatured alcohol before adding threadlocker gm p/n 12345493 (Canadian P/N 10953488) to the threads. Insert and tighten the Brake Caliper Bracket bolts to 180 nm (133 ft lbs). Then position the anti-rattle clips and install the brake pads on the rotor surface. Push the caliper onto its bracket and fasten it by tightening the brake caliper bolts to 100 nm. Reposition the tire and wheel parts then let the vehicle down and press the brake pedal halfway without starting the engine before easing off the pressure. Keep repeating the test until the pedal feels solid and add clean brake fluid to reach the correct reservoir level when necessary.
