Component Name

Warning: Refer to Brake Dust Warning in the Preface section.

Caution: 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.

Preliminary Procedures

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
  2. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation.
  3. Remove the brake caliper and bracket as an assembly and support with heavy mechanics wire or equivalent. Refer to Front Brake Caliper Bracket Replacement.

Procedure

  1. If installing a new brake rotor, clean the friction surfaces of the brake rotor with denatured alcohol.
  2. If reinstalling the original brake rotor, mark the relationship of the rotor to the wheel hub.
  3. Using the J 42450-A , thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
  4. Using the J 41013 , thoroughly clean any rust or corrosion from the mating surface of the rotor to the hub/axle flange.
  5. If the brake rotor is to be machined, check the thickness variation measurement. Refer to Brake Rotor Thickness Variation Measurement.
  6. After installing the brake rotor, measure the assembled lateral runout (LRO) of the brake rotor. Refer to Brake Rotor Assembled Lateral Runout Correction.
  7. If the brake rotor assembled LRO measurement exceeds specification, bring the LRO to within specification. Refer to Brake Rotor Assembled Lateral Runout Correction - Indexing.
  8. If the brake rotor was refinished or replaced, burnish the pads and rotors. Refer to Brake Pad and Rotor Burnishing.
