NOTE
In order for the rear pads to seat in the caliper properly, the cut outs in the caliper piston must be at the 6 and 12 o'clock positions. Failure to align the piston correctly can lead to brake drag, premature brake wear and possible brake failure.

  1. Using a suitable type spanner tool turn the piston in to bottom the piston fully into the caliper bore. Once the caliper is fully seated make sure the cutouts in the piston are at the 6 and 12 o'clock positions.
  2.  
  3. After bottoming the piston into the caliper bore, lift the inner edge of boot next to the piston assembly and press out any trapped air.
  4.  
  5. Install 2 pad clips in the caliper support.
  6.  
  7. Lubricate the inner pad where it contacts the piston and mounting surfaces.
  8.  
  9. Install outboard and inboard shoe and linings in caliper support. Position the wear sensors downward at the leading edge of the rotor during forward wheel rotation.
  10.  
  11. Hold the metal shoe edge against the spring end of clips in the caliper support. Push brake pad in towards the hub, bending spring ends slightly and engage shoe notches with support abutments.
  12.  
  13. Pivot the caliper body assembly down over the brake pad. Compress the sleeve boot by hand as the caliper body moves into position to prevent boot damage.
    NOTE
    After the caliper body assembly is in position, recheck installation of the brake pad clips. If necessary, use a small prying tool to reseat or center the pad clip on the support abutments.

  14.  
  15. Install the sleeve bolts and torque bolt to 20 ft. lbs. (27 Nm).
  16.  
  17. Install the cable support bracket with the cable attached and bolt washer. Torque bolt to 32 ft. lbs. (43 Nm).
  18.  
  19. Remove the 2 lug nuts securing the rotor.
  20.  
  21. Install the tire and wheel assembly and tighten to specification.
  22.  
  23. Pump the brake pedal several times to seat the pads against the rotor.
  24.  
  25. Check the brake fluid level and top off as necessary.
  26.  
  27. Adjust parking brake as necessary.
  28.  
  29. Road test the vehicle for proper brake performance.
  30.

CAUTION
Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Siphon 2 / 3 of the brake fluid out of the master cylinder.

  6.  
  7. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
  8.  
  9. Raise and support the vehicle.
  10.  
  11. Remove the tire and wheel assembly.
  12.  
  13. Release tension from park brake system at the equalizer.
