  1. Siphon 2 / 3 of the brake fluid from the master cylinder reservoir. Loosen the wheel lug nuts and raise the car. Remove the wheel.
  2.  
  3. Position a C-clamp across the caliper so that it presses on the pads and tighten it until the caliper piston bottoms in its bore.
  4.  

If you haven't removed some brake fluid from the master cylinder, it will overflow when the piston is retracted.

  1. Remove the C-clamp.
  2.  
  3. Remove the allen head caliper mounting bolts. Inspect the bolts for corrosion, and replace as necessary.
  4.  
  5. Remove the caliper from the steering knuckle and suspend it from the body of the car with a length of wire. Do not allow the caliper to hang by its hose.
  6.  
  7. Remove the pad retaining springs and remove the pads from the caliper.
  8.  
  9. Remove the plastic sleeves and the rubber bushings from the mounting bolt holes.
  10.  

To install:

  1. Install new sleeves and bushings. Lubricate the sleeves with a light coating of silicone grease before installation. These parts must always be replaced when the pads are replaced. The parts are usually included in the pad replacement kits.
  2.  
  3. Install the outboard pad into the caliper.
  4.  
  5. Install the retainer spring on the inboard pad. A new spring should be included in the pad replacement kit.
  6.  
  7. Install the new inboard pad into the caliper. The retention lugs fit into the piston.
  8.  
  9. Use a large pair of slip joint pliers to bend the outer pad ears down over the caliper.
  10.  
  11. Install the caliper onto the steering knuckle. Tighten the mounting bolts to 21-35 ft. lbs. (28-47 Nm). Install the wheel and lower the car. Fill the master cylinder to its proper level with fresh brake fluid meeting DOT 3 specifications. Since the brake hose wasn't disconnected, it isn't really necessary to bleed the brakes, although most mechanics do this as a matter of course.

INSPECTION



The pad thickness should be inspected every time that the tires are removed for rotation. The outer pad can be checked by looking in at each end, which is the point at which the highest rate of wear occurs. The inner pad can be checked by looking down through the inspection hole in the top of the caliper. If the thickness of the pad is worn to within 0.030 in. (0.76 mm) of the rivet at either end of the pad, all the pads should be replaced. This is the factory-recommended measurement; your state's automobile inspection laws may not agree with this.

Always replace all pads on both front wheels at the same time. Failure to do so will result in uneven braking action and premature wear.
