Removal (Rear - Without Dual Wheels & 4-Wheel Steering)

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, and 2003 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.
  1. Release the park brake.
  2. Raise and support the vehicle.
  3. Remove the tire and wheel assembly.
  4. Mark the relationship of the rotor to the hub.
  5. 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.
  6. Slowly tighten the C-clamp until the pistons are pushed into the caliper bores enough to remove the caliper from the pads.
  7. Remove the C-clamp from the caliper.
  8. Remove the brake caliper bracket mounting bolts.
    CAUTION: 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.
  9. Remove the brake caliper and brake caliper bracket as an assembly and support with heavy mechanic's wire or equivalent. Do not disconnect the hydraulic brake flexible hose from the caliper.
  10. Remove the rotor retaining push nuts from the wheel studs, if applicable.
  11. 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. Remove the rotor by slowly turning the rotor while pulling the rotor away from the axle. See Fig 1.
  13. If the brake rotor cannot be removed perform the following:
    1. Assemble Rotor Removal Tool (J-46277) to Slide Hammer With Adapter (J-2619-01). See Fig 2.
    2. Insert rotor removal tool between the rotor friction surfaces in the vent section of the rotor. Do not place the rotor removal tool on the rotor friction surface.
    3. Using rotor removal tool and slide hammer with adapter remove the rotor from the hub assembly.
    4. Inspect the park brake components for the following conditions:
      • Bent or broken hold down spring.
      • Broken, cracked or worn brake shoe lining.
      • Bent or damaged brake shoe.
      • Worn, bent or damaged backing plate.
    5. If any of these conditions are found replace the affected parts.
