WARNING
Before beginning the procedure, determine whether your vehicle is equipped with a rear parking brake assembly. If equipped with rear parking brakes, only compress the piston slightly, or the piston screw could be damaged.

  1. Remove as much brake fluid as possible from the master cylinder reservoir.
  2.  
  3. Raise and support the vehicle safely on jackstands. Remove the rear wheels.
  4.  
  5. Use a C-clamp to compress the piston into the caliper bore.
    NOTE
    If your vehicle is equipped with rear parking brakes, compress the piston only slightly.

  6.  
  7. Release the parking brake and disconnect the cable from the caliper lever, if equipped.
  8.  
  9. Remove the brake hose from the caliper body and plug the hose to prevent the entrance of dirt or moisture.
  10.  
  11. Remove the caliper bracket retainer bolts.
  12.  
  13. Slide the caliper and bracket assembly off the spindle and rotor.
  14.  
  15. Remove the brake pads, backing plate and retainer clips.
  16.  
  17. Compress the piston assembly into the cylinder bore.
    NOTE
    If equipped with a parking brake, use a suitable tool to rotate the piston back into the caliper bore.

  18.  

To install:

  1. Install the caliper bracket to the spindle assembly, and secure in place with the retainer bolts. Tighten the retainer bolts to 12-17 ft. lbs. (16-22 Nm).
