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. Raise and support the vehicle.
  2.  
  3. Remove the tire and wheel assembly.
    WARNING
     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.

  4.  
  5. Remove the brake caliper and bracket from the vehicle, support the caliper assembly away from the rotor.
  6.  
  7. Mark the relationship of the rotor to the hub.
  8.  
  9. Remove the brake rotor.
  10.  

To install:


NOTE
Whenever the rotor has been separated from the wheel bearing flange, clean any rust or contaminants from the wheel bearing flange and the brake rotor mating surfaces. Failure to do this may result in increased lateral runout of the brake rotor, and brake pulsation.

  1. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  2.  
  3. Install the brake rotor to the hub/axle flange. Use the matchmark made prior to removal for proper orientation to the flange.
  4.  
  5. Install the brake caliper and bracket assembly.
  6.  
  7. Install the tire and wheel assembly.
  8.  
  9. Lower the vehicle.
  10.

CAUTION
Two different designs of the brake rotors and brake pads are used on this vehicle. Do NOT interchange first design and second design parts, or a loss of braking and personal injury could occur. Service procedures are the same for both types.
