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.
  2.  
  3. Remove the caliper from the mounting bracket but do not disconnect the brake hose and inlet fitting assembly.
  4.  
  5. Suspend the caliper from the upper control arm with wire to avoid damage to the brake hose.
  6.  
  7. Remove the pad and lining assemblies from the caliper.
  8.  

To install:

  1. Clean all residue from the pad and lining assembly guiding surfaces on the caliper housing and the mounting bracket.
  2.  
  3. 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.
  4.  
  5. Remove the support and install the caliper to the mounting bracket.
  6.  
  7. Connect the negative battery cable.
  8.  

With J56 Brake System
  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 from the reservoir 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 suitably support the vehicle
  4.  
  5. Remove the tire and wheel assembly.
  6.  
  7. Remove the 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 pads from the housing.
  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, if equipped.
  2.  
  3. Hand install the disc brake pad pins while gently rocking the disc brake pads. The pins should require little effort to install.
    1. Repeat previous 2 steps to install the center and trailing pads.
    2.  

  4.  
  5. Tighten brake pad pins to 30 ft. lbs.(40 Nm).
  6.  
  7. Install the tire and wheel assembly.
  8.  
  9. Lower the vehicle.
  10.  
  11. With the engine OFF:
    1. Gradually apply the brake pedal to approximately 2/3 of its travel distance.
    2.  
    3. Slowly release the brake pedal.
    4.  
    5. Wait 15 seconds, then repeat steps 11-12 until a firm brake pedal apply is obtained. This will properly seat the brake caliper pistons and brake pads.
    6.  

  12.  
  13. Fill the brake master cylinder reservoir to the proper level.
  14.  
  15. Burnish the pads and rotors.

Without J56 Brake System
  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 from the reservoir 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 suitably support the vehicle
  4.  
  5. Remove the tire and wheel assembly.
  6.  
  7. Hand tighten a wheel lug nut to a wheel stud to secure the rotor to the hub.
  8.  
  9. Install a large C-clamp over the body of the brake caliper with the C-clamp ends against the rear of the caliper body and against the outboard brake pad.
  10.  
  11. Tighten the C-clamp evenly until the caliper pistons are compressed into the caliper bores enough to allow the caliper to slide past the brake rotor.
  12.  
  13. Remove the C-clamp from the caliper.
  14.  
  15. Remove the upper brake caliper guide pin bolt.
    NOTE
    Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.

  16.  
  17. Pivot the brake caliper body downward and secure the caliper out of the way with heavy mechanic's wire or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose.
    CAUTION
    Do NOT disconnect the hydraulic brake flexible hose from the caliper.

  18.  
  19. Remove the brake pads from the caliper bracket.
  20.  
  21. Remove and inspect the brake pad retainers from the caliper bracket.
  22.  

To install:

  1. Inspect the caliper slide boots for cuts, tears, or deterioration. If damaged, replace the slides and the boots.
  2.  
  3. Install the brake pad retainers to the caliper bracket.
  4.  
  5. Install the brake pads to the caliper bracket. The brake pad wear sensor, mounted on the inboard brake pad, must be positioned so that it is in the leading bottom position during forward rotation of the brake rotor.
  6.  
  7. Pivot the brake caliper upward, over the brake pads and into the caliper bracket.
  8.  
  9. Install the upper brake caliper guide pin bolt.
  10.  
  11. Tighten the brake caliper guide pin bolt to 23 ft. lbs.(31 Nm).
  12.  
  13. Install the tire and wheel assembly.
  14.  
  15. Lower the vehicle.
