• | Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad. |
• | Slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores. |
• | Remove the C-clamp from the caliper. |
Important: Install a rubber cap or plug to the exposed brake pipe fitting end to prevent brake fluid loss and contamination.
Important: Use denatured alcohol to clean the outside surface of caliper boots before installing new brake pads.
Important: Use a small flat-bladed tool and lift the inner edge of the caliper boots next to both pistons to release any trapped air.
4.1. | Remove all traces of the original adhesive patch. |
4.2. | Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry. |
4.3. | Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt. |
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.
