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 battery negative cable from battery and properly isolate to prevent accidental reconnection.
    NOTE
    Always turn the ignition OFF when connecting or disconnecting battery cables, battery chargers, or jumper cables. Failing to do so may damage the Powertrain Control Module (PCM) or other electronic components.


    NOTE
    The battery is located beneath the rear seat cushion.

  4.  
  5. Raise and support the vehicle.
  6.  
  7. Remove the tire and wheel assembly.
  8.  
  9. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.
  10.  
  11. Using the C-clamp, compress the piston into the caliper bore just enough to allow the caliper to slide away from the rotor.
  12.  
  13. Remove the C-clamp.
    NOTE
    Support the brake caliper with heavy mechanic's 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.

  14.  
  15. Remove the brake caliper and the caliper mounting bracket as an assembly from the suspension knuckle and support the assembly with heavy mechanic's wire, or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose.
  16.  
  17. Mark the relationship of the rotor to the hub.
  18.  
  19. Remove the brake rotor.
  20.  

To install:


NOTE
Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.

  1. Thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange and brake rotor.
  2.  
  3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  4.  
  5. Install the brake rotor to the hub/axle flange. Use the matchmark made prior to removal for proper orientation to the flange.
  6.  
  7. Install the brake caliper bracket assembly.
  8.  
  9. Install the brake caliper to the brake caliper bracket assembly.
  10.  
  11. Install the tire and wheel assembly.
  12.  
  13. Lower the vehicle.
  14.  
  15. If the brake rotor was refinished or replaced, or if new brake pads were installed, burnish the pads and rotors.
