Installation Procedure
- If you are installing new brake pads use a C-clamp in order to compress the pistons to the bottom of the caliper bores. Use the old brake pad, a metal plate or a wooden block across the face of the pistons in order to protect the pistons and the caliper boots.
- Ensure that the caliper boots are below the level of the face of both pistons.
- Install the brake caliper to the brake caliper mounting bracket.
- Perform the following procedure before installing the caliper guide pin bolts.
- Remove all traces of the original adhesive patch.

- Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt.
- Install the brake caliper mounting bolts.
- Tighten the brake caliper guide pin bolts.
Tighten: Tighten the brake caliper guide pin bolts to 108 N.m (80 lb ft).
- Remove the rubber cap or plug from the exposed brake hose fitting end.
- Assemble the 2 new copper brake hose gaskets and the brake hose to caliper bolt to the brake hose.
- Connect the brake hose at the caliper by installing the brake hose to caliper bolt.
Tighten: Tighten the brake hose to caliper bolt to 40 N.m (30 lb ft).
- Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding (Manual) or Hydraulic Brake System Bleeding (Pressure) .
