REMOVAL & INSTALLATION



See Figures 1, 2 and 3


CAUTION
Brake pads or shoes may contain asbestos, which has been determined to be cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

  1. Loosen the wheel lug nuts slightly.
  2.  
  3. Raise and support the vehicle safely.
  4.  
  5. Remove the wheels.
  6.  
  7. Disconnect the brake hose from the caliper. Plug the end of the hose to prevent loss of fluid. Some brake lines have a union bolt and gasket type line attached to the caliper. Do not loose the washers.

OVERHAUL



See Figures 4, 5, 6, 7, 8, 9, 10 and 11

Some vehicles may be equipped dual piston calipers. The procedure to overhaul the caliper is essentially the same with the exception of multiple pistons, O-rings and dust boots.

  1. Remove the caliper from the vehicle and place on a clean workbench.
  2.  


CAUTION
NEVER place your fingers in front of the pistons in an attempt to catch or protect the pistons when applying compressed air. This could result in personal injury!

Depending upon the vehicle, there are two different ways to remove the piston from the caliper. Refer to the brake pad replacement procedure to make sure you have the correct procedure for your vehicle.

  1. The first method is as follows:
    1. Stuff a shop towel or a block of wood into the caliper to catch the piston.
    2.  
    3. Rmove the caliper piston using compressed air applied into the caliper inlet hole. Inspect the piston for scoring, nicks, corrosion and/or worn or damaged chrome plating. The piston must be replaced if any of these conditions are found.
