Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Raise and support vehicle.
  4.  
  5. Remove wheel mounting nuts, then tire and wheel assembly.
    NOTE
    In some cases, it may be necessary to retract caliper piston in its bore a small amount in order to provide sufficient clearance between shoes and rotor to easily remove caliper from knuckle. This can usually be accomplished before guide pin bolts are removed, by grasping rear of caliper and pulling outward working with guide pins, thus retracting piston. Never push on piston directly as it may get damaged.
