  1. Using a C-clamp (1), bottom the piston into the caliper bore. Use an old brake pad (2) or wooden block placed across the face of the piston. Do not damage the piston or the caliper boot
    IMPORTANT: Use a small flat-bladed tool and lift the inner edge caliper boot next to the piston to release any trapped air

  4. Install the brake pads over the brake pad retainers and onto the caliper bracket.
  5. Install the caliper to the caliper mounting bracket.
    NOTE: 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.
  6. Install 2 new caliper guide pin bolts. Tighten Tighten the 2 caliper guide pin bolts to 42 N.m (31 lb ft).
  7. Install the tire and wheel assembly.
  8. Lower the vehicle.
