To install:
  1. Clean all residue from the pad guide surfaces on the mounting bracket and caliper housing. Inspect the guide pins for free movement in the mounting bracket. Replace the guide pins or boots, if they are corroded or damaged.
  2.  
  3. Install a new brake pad anti-squeal shim.
  4.  
  5. Install the disc brake pads. The outboard pad with insulator is installed toward the caliper housing. The inboard pad with the wear sensor is installed nearest the caliper piston. The wear sensor must be in the leading position with forward wheel rotation. If not, use the other inner pad in the replacement kit.
  6.  
  7. Rotate the caliper housing into it's operating position. The springs on the outboard brake pad must not stick through the inspection hole in the caliper housing. If the springs are sticking through the inspection hole in the caliper housing, lift the caliper housing and make the necessary corrections to the outboard brake pad positions.
  8.  
  9. Install a caliper guide pin bolt and tighten to 27 ft. lbs. (37 Nm). Tighten the lower caliper guide pin bolt to 16 ft. lbs. (22 Nm). Check that the caliper guide pin boot is properly seated in the retaining groove of the caliper guide pin and mounting plate.
  10.  
  11. With the engine running, pump the brake pedal slowly and firmly to seat the brake pads.
  12.  
  13. Check the caliper parking brake levers to make sure they are against the stops on the caliper housing. If the levers are not on their stops, check the parking brake adjustment.
  14.  
  15. Remove the 2 lug nuts from the rotor, then install the wheel and tire assembly.
  16.
