Caution: Refer to Brake Dust Caution in the Preface section.
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.
Important: If reusing the caliper bracket bolts the threads of the caliper bracket bolts and the threads of the knuckle mounting holes must be free of residue and debris prior to application of threadlocker in order to ensure proper adhesion and fastener retention.
2.1. | Thoroughly clean the residue from the bolt threads by using denatured alcohol or equivalent and allow to dry. |
2.2. | Thoroughly clean the residue from the threaded holes by using denatured alcohol or equivalent and allow to dry. |
2.3. | Apply threadlocker GM P/N 12345493 (Canada 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. |
2.4. | Allow the threadlocker to cure approximately ten minutes before installation. |
Notice: Refer to Fastener Notice in the Preface section.
