Removal & Installation




CAUTION
Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Remove the wheel.
  6.  
  7. Install a large C-clamp over the body of the caliper with the clamp ends against the rear of the caliper body and against the outboard pad. Tighten the clamp evenly to compress the pistons.
  8.  
  9. Remove the upper caliper bolt, then pivot the caliper downwards until enough clearance is achieved and support the caliper with wire.
  10.  
  11. Remove the pad and lining assemblies from the caliper.
  12.  

To install:

  1. Clean all residue from the pad and lining assembly guiding surfaces on the caliper housing and the mounting bracket.
  2.  
  3. Ensure the caliper pistons are fully compressed in their bores.
  4.  
  5. Install the outboard pad with the insulator to the caliper housing and the inboard pad with the wear sensor into the caliper pistons. Press the pads firmly until they are they are fully seated.
  6.  
  7. Install the caliper in position, insert and tighten the upper bolt to 23 ft. lbs. (31 Nm).
  8.  
  9. Install the wheel.
  10.  
  11. Connect the negative battery cable.
  12.  

  1. Disconnect the negative battery cable and remove 2 / 3 of the brake fluid from the master cylinder reservoirs.
  2.  
  3. Mark the relationship between the wheel to the axle flange.
  4.  
  5. Remove the tire and wheel assembly. Install 2 wheel nuts to retain the brake rotor.
  6.  
  7. Use a C-clamp to depress the caliper pistons into the caliper bores to provide clearance between the pads and the rotor. Make sure 1 end of the clamp rests on the inlet fitting bolt while the other end rests on the outboard pad.
  8.  
  9. Remove the caliper upper guide pin bolt and discard, then rotate the caliper on the lower guide pin to access the pad linings. Be careful not to strain the cable conduit or the hoses.
  10.  
  11. Remove the pads from the caliper.
  12.  

To install:

  1. Install the outboard pad with the insulator to the caliper housing and the inboard pad with the wear sensor nearest the caliper pistons. The wear sensor must be in the trailing position during forward wheel rotation. Press the pads firmly until they are they are fully seated.
  2.  
  3. Rotate the caliper housing into position, then install a new upper guide pin bolt and torque 26 ft. lbs. (35 Nm).
  4.  
  5. Remove the wheel nuts securing the rotor to the hub and install the tire and wheel assembly.
  6.  
  7. Fill the master cylinder to the proper level with clean brake fluid.
  8.  
  9. Connect the negative battery cable, start the engine and pump the brake pedal slowly and firmly 3 times to seat the shoe and lining assemblies.
  10.

  1. Inspect the fluid level in the brake master cylinder reservoir.
    1. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed before proceeding.
    2.  
    3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
    4.  

  2.  
  3. Raise and support the vehicle.
  4.  
  5. Remove the tire and wheel assembly.
  6.  
  7. Remove both outboard and inboard disc brake pad pins
  8.  
  9. Using a brake pad spreader tool, compress the brake caliper pistons into the caliper bores.
  10.  
  11. Remove the leading and trailing brake pads.
  12.  

To install:

  1. Install the leading disc brake pads with the wear sensors on the trailing edge of the brake pad during forward wheel rotation.
  2.  
  3. Hand install the disc brake pad pins while gently rocking the disc brake pads. The pins should require little effort to install.
  4.  
  5. Tighten the disc brake pad pins to 30 ft. lbs. (40 Nm).
  6.  
  7. Install the tire and wheel assembly.
  8.  
  9. Lower the vehicle.
  10.  
  11. After the installation is complete and with the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
  12.  
  13. Slowly release the brake pedal.
  14.  
  15. Wait 15 seconds, then repeat steps 3-4 until a firm brake pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
  16.  
  17. Fill the master cylinder reservoir to the proper level.
  18.  
  19. Burnish the brake pads and rotors.
