GM 89027180
Caliper Mount

The vehicle requires a lift and tire assembly removal before starting to replace the front Brake Caliper Bracket. Then unscrew the brake caliper guide pin bolts while keeping the brake caliper hose connected. Pull out the brake caliper by supporting it with heavy mechanics wire or equivalent. Start by subtracting Brake Pad seizers from both sides of the brake caliper and then record the sensor position for future assembly before removing Brake Pad shims and Brake Caliper Bracket bolts. Remove the Brake Caliper Bracket after you remove the Brake Caliper Bracket bolts. Begin installation by installing the Brake Caliper Bracket followed by proper tightening of the Brake Caliper Bracket bolts to 160 nm (118 lb ft). Install both Brake Pad shims and inner and outer brake pads while making sure wear sensors find their correct spots. Decide to locate your brake caliper on the bracket followed by fitment of relaxed brake caliper guide pin bolts. Complete installation with torque to 42 nm (31 lb ft) for the upper brake caliper guide pin bolt and 42 nm (31 lb ft) for the lower brake caliper guide pin bolt. Reinstall the tire along with the wheel assembly then lower the vehicle down.

Inspect the brake caliper assembly and support it with heavy mechanic's wire or an equivalent while it is separated from its mount, ensuring the hydraulic flexible brake hose remains connected.

Attach the rear brake pad hardware, followed by the brake pads.

To prevent damage to the hose and potential brake fluid leaks.

Install the rear brake pad hardware and the brake pads to the brake caliper mounting bracket.

Place the guide pin seals on the mounting bracket, clean the guide pins and brake pad retaining clips with denatured alcohol if they are to be reused, and dry them with non-lubricated, filtered air.

Inspect the brake hardware and remove the brake pad retaining clips from the mounting bracket.

Attach the front brake pad hardware and brake pads.

Reinstall the tire and wheel assembly, and finally lower the vehicle.

Place the guide pin seals on the mounting bracket.

Inspect the brake pads and remove them from the mounting bracket, focusing on the inboard brake pad.

Attach the rear brake pad hardware to the mounting bracket, followed by the brake pads.

Ensure the brake caliper assembly is supported to avoid damaging the hose and causing a brake fluid leak.

Attach the rear brake pad hardware to the brake caliper mounting bracket, followed by the brake pads.

First, raise the vehicle and remove the tire and wheel assembly.

Clean them with denatured alcohol and dry them with non-lubricated, filtered air.

Remove the front brake pads from the mounting bracket and inspect the brake hardware.
