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.
• | Remove all traces of the original adhesive patch. |
• | Clean the threads of the bolts with brake parts cleaner or the equivalent and allow to dry. |
• | Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolts. |
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.
Tighten
Tighten the 2 brake caliper mounting bracket bolts to 200 N·m
(148 lb ft).
