    CAUTION
    Brake pads may 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. Using a clean turkey baster or equivalent, remove about 2 /3 of the brake fluid from the master cylinder.
    2.  
    3. Raise and safely support the vehicle.
    4.  
    5. Remove the tire and wheel assembly.
    6.  
    7. Using a C-clamp, bottom the piston in its bore for clearance to remove it from the rotor.
    8.  
    9. Remove the caliper from the steering knuckle by removing the two bolts.
    10.  
    11. Lift the caliper from the rotor and steering knuckle.
    12.  
    13. Using a piece of wire, support the caliper in a position that will allow the pads to be removed.
    14.  
    15. Use a suitable prytool to disengage the buttons on the outboard pad from the holes in the caliper housing, then remove the outboard pad.
    16.  
    17. Remove the inboard pad.
    18.  
    19. Prior to installing new pads, wipe the outside surface of the boot clean with denatured alcohol.

    Fig. Fig. 8: Install the inboard pad engaging the retaining spring on the back of the pad into the caliper piston

    To install:
    1. Before installing the inboard pad, lift the inner edge of the boot next to the piston and press out any trapped air. The boot must lie flat.
    2.  
    3. Using a wire brush, clean the pad contact areas of the steering knuckle and caliper.
    4.  
    5. Install the inboard pad by snapping the pad retaining spring into the piston inside diameter. The pad retainer spring is already staked to the inboard pad. After installing the pad, make sure the boot is not touching the pad. If there is contact, reseat or reposition the boot.
    6.  
    7. Install the outboard pad with the wear sensor at the trailing edge of the caliper.
    8.  
    9. Install caliper to the steering knuckle.
    10.  
    11. Clean the caliper bolts and sleeves, then liberally coat the inside of the bushings with silicone grease.
    12.  
    13. Tighten the caliper mounting bolts to 38 ft. lbs. (51 Nm)
    14.  
    15. Install the tire and wheel assembly.
    16.  
    17. Carefully lower the vehicle, then fill the master cylinder to the proper level.
    18.  
    19. Push the brake pedal down until the pads seat and the pedal effort becomes hard.
    20.

    CAUTION
    Do NOT attempt to drive the vehicle until the pads are seated. The master cylinder cannot displace enough brake fluid to seat the pads and provide stopping power in one stroke. The brake pedal may require several applications before normal braking action is obtained.

    INSPECTION



    1. Inspect the brake linings approximately every 6,000 miles or whenever the wheels are removed.
    2.  
    3. Check both ends of the pad for uneven wear.
    4.  
    5. Check the lining thickness on the inner pad to make sure it is wearing evenly.
    6.  

    Some inboard pads have a thermal lining against the pad, molded integrally with the lining. Do not confuse this lining with uneven inboard-outboard lining wear.

    1. Whenever the thickness of the lining is worn to the wear indicator, the pads must be replaced.
    2.
