CAUTION
Brake pads contain asbestos, which has been determined to be a 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. To remove the brake caliper, refer to the Rear Caliper Removal procedure.
  2.  
  3. Remove the brake pads from the calipers. Remove the sleeves from the mounting bolts and the bushings from the caliper.
  4.  
  5. Using a small screwdriver, remove the 2-way check valve from the end of the piston. Clean and check the valve for leakage.
  6.  

If leakage is noted, the caliper must be overhauled.

To install:
  1. Position the brake pads into the caliper. Lubricate and install new bushings, sleeves and check valve.
  2.  
  3. When installing the inner brake pad, make sure that the D-shaped tab of the pad engages with the D-shaped notch of the piston, as illustrated.
  4.  
  5. Upon installation of the inner pad, make sure that the wear sensor of the pad is at the leading edge of the shoe during forward wheel rotation. Slide the metal edge of the pad under the ends of the dampening spring and snap the pad into position against the piston.
  6.  
  7. Install the outer pad and caliper. After installing the caliper, apply the brakes, then bend the ears of the outer pad against the caliper and ensure that there is no excessive clearance.

  1. Remove 2 / 3 of the brake fluid from the master cylinder reservoir.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. Remove the wheel and tire assembly. Install 2 wheel nuts to retain the rotor.
  6.  
  7. Position a C-clamp and tighten until the piston bottoms in the base of the caliper housing. Make sure 1 end of the C-clamp rests on the inlet fitting bolt and the other against the outboard disc brake pad.
  8.  

It is not necessary to remove the parking brake caliper lever return spring to replace the disc brake pads.

  1. Remove the upper caliper guide pin bolt and discard.
  2.  
  3. Rotate the caliper housing. Be careful not to strain the hose or cable conduit.
  4.  
  5. Remove the disc brake pads.
  6.  

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 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 trailing position with forward wheel rotation.
  4.  
  5. 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.
  6.  
  7. Install a new upper caliper guide pin bolt and tighten to 26 ft. lbs. (35 Nm). Tighten the lower caliper guide pin bolt to 16 ft. lbs. (22 Nm).
  8.  
  9. With the engine running, pump the brake pedal slowly and firmly to seat the brake pads.
  10.  
  11. 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.
  12.  
  13. Remove the 2 wheel nuts from the rotor and install the wheel and tire assembly.
  14.  
  15. Lower the vehicle, check the master cylinder fluid level and road test the vehicle.
  16.
