Removal & Installation



The brake rotor can be removed without separating the caliper from the mounting bracket.

  1. Release the parking brake.
  2.  
  3. Remove 2 / 3 of the brake fluid from the master cylinder.
  4.  
  5. Raise and support the vehicle.
  6.  
  7. Remove the tire and wheel assembly.
  8.  
  9. Remove the caliper and mounting bracket as an assembly.
  10.  
  11. Hang the caliper and mounting bracket assembly from the suspension using mechanics wire.
  12.  
  13. Remove the rotor. Slowly turn the rotor while pulling the rotor away from the axle.
    NOTE
    If the rotor is stuck to the hub, try using a slide hammer to free it.

To install:


WARNING
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 run-out (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.
  2.  
  3. Thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor.
  4.  
  5. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  6.  
  7. Install the rotor. Slowly turn the rotor while pushing the rotor towards the axle.
  8.  
  9. Install the caliper and the mounting bracket as an assembly.
  10.  
  11. Install the tire and wheel assembly.
  12.  
  13. Lower the vehicle.
  14.  

With Quadrasteer (Nys)

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. Release the park brake.
  2.  
  3. Raise and suitably support the vehicle.
  4.  
  5. Remove the tire and wheel.
  6.  
  7. Mark the relationship of the rotor to the hub.
  8.  
  9. Remove the brake caliper and brake caliper mounting bracket as an assembly and support with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper.
    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.

  10.  
  11. Remove the rotor retaining push nuts from the wheel studs, if applicable.
    NOTE
    It may be necessary to strike the end of the hub or the rotor with a deadblow hammer to separate the rotor from the hub.

  12.  
  13. Remove the rotor by slowly turning the rotor while pulling the rotor away from the axle.

Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to 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. Align the rotor to its original position on the hub, if applicable.
  4.  
  5. Install the rotor by slowly turning the rotor while pushing the rotor towards the axle.
  6.  
  7. If the brake rotor was removed and installed as part of a brake system repair, measure the assembled lateral runout (LRO) of the brake rotor to ensure optimum performance of the disc brakes.
  8.  
  9. Install the brake caliper and the brake caliper mounting bracket as an assembly to the vehicle.
  10.  
  11. Install the brake caliper bracket mounting bolts.
  12.  
  13. Tighten the brake caliper bracket mounting bolts to 148 ft. lbs. (200 Nm).
  14.  
  15. Install the tire and wheel.
  16.  
  17. Lower the vehicle.
  18.  
  19. With the engine OFF gradually apply the brake pedal to approximately 2 / 3 of its travel distance.
  20.  
  21. Slowly release the brake pedal.
  22.  
  23. Wait 15 seconds then repeat steps until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
