WARNING
Before beginning the procedure, determine whether your vehicle is equipped with a front parking brake assembly. If equipped with front 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 front wheels.
  4.  
  5. Use a C-clamp to compress the piston into the caliper bore.
    NOTE
    If your vehicle is equipped with front 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.
