Front Brake Caliper Bracket Replacement without J55
Caution: Refer to Brake Dust Caution in the Preface section.
Removal Procedure
Notice: Support the brake caliper with heavy mechanic 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.
- 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. Refer to
Front Brake Caliper Replacement
.
- Remove the brake pads (1) from the
brake caliper bracket (3).
- Remove the brake pad retainers (2) from the brake caliper bracket (3).
- Remove the brake caliper bracket bolts (1).
- Remove the brake caliper bracket.
- Use a wire brush to clean any debris or rust from the brake caliper bracket.
- Inspect the brake mounting and hardware. Refer to
Front Disc Brake Hardware Replacement
.
- Inspect the brake caliper bracket for cracks or damage.
- 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. |
- Install the brake caliper bracket to the steering knuckle.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the brake caliper bracket bolts (1).
Tighten
Tighten the brake caliper bracket bolts to 185 N·m
(137 lb ft).
- Apply a thin coat of NIGLUBE® to the brake caliper pin bolts.
- Install the brake pad retainers (2)
to the brake caliper bracket (3).
- Install the brake pads (1) to the brake caliper bracket (3).
- Install the brake caliper. Refer to
Front Brake Caliper Replacement
