Brake Caliper Bracket Replacement - Front (without J55)

Caution: Refer to Brake Dust Caution.

Removal Procedure





Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.

1. Remove the brake caliper from the mounting bracket and support the brake caliper (2) with heavy mechanic's wire (1), or equivalent; do NOT disconnect the hydraulic brake flexible hose from the caliper.





2. Remove the brake pads (1) from the brake caliper bracket (3).
3. Remove the brake pad retainers (2) from the brake caliper bracket (3).





4. Remove the brake caliper bracket bolts (1).
5. Remove the brake caliper bracket.
6. Use a wire brush to clean any debris or rust from the brake caliper bracket.
7. Inspect the brake mounting and hardware.
8. Inspect the brake caliper bracket for cracks or damage.
9. Replace the brake caliper bracket if cracked or damaged.

Installation Procedure





Important: The brake caliper bracket bolts threads and the threaded holes of the brake caliper bracket must be free of residue and debris prior to reapplication of threadlocker in order to ensure proper adhesion and fastener retention.

^ Prepare the bolts and the threaded holes for assembly:
^ Thoroughly clean the residue from the bolt threads by using denatured alcohol or equivalent and allow to dry.
^ Thoroughly clean the residue from the threaded holes by using denatured alcohol or equivalent and allow to dry.
^ Apply threadlocker GM P/N 12345493 (Canadian P/N 10953488) or equivalent to two-thirds of the threaded length of the lower caliper bracket bolts. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolts.
^ Allow the threadlocker to cure approximately ten minutes before installation.

1. Install the brake caliper bracket to the steering knuckle.

Notice: Refer to Fastener Notice.

2. Install the brake caliper bracket bolts (1).
^ Tighten the brake caliper bracket bolts to 185 Nm (137 lb ft).





3. Apply a thin coat of NIGLUBE to the brake caliper pin bolts.
4. Install the brake pad retainers (2) to the brake caliper bracket (3).
5. Install the brake pads (1) to the brake caliper bracket (3).
