Removal (Front)

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. Raise and support the vehicle.
  2. Remove the tire and wheel assembly.
  3. Remove the front wheel hub extension (dual wheel vehicles only).
    1. Insert a drift or large screwdriver through the brake caliper into one of the brake rotor vanes in order to prevent the rotor from turning.
    2. Mark the relationship of the front wheel hub extension to the hub.
    3. Remove the front wheel hub extension bolts.
    4. Remove the front wheel hub extension from the vehicle. It may be necessary to tap around the perimeter of the hub extension with a rubber mallet to loosen it from the hub.
  4. Mark the relationship of the rotor to the hub.
  5. 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.
  6. 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.
  7. Remove the rotor retaining push nuts from the wheel studs, if applicable.
  8. 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.
  9. Remove the rotor. See Fig 1.
  10. If the rotor is difficult to remove due to corrosion in the hub area use the following procedure to remove the rotor (2500 and 3500 series only).
    1. Clean all the surface areas and the threaded holes of contamination.
    2. Generously apply penetrating oil or the equivalent to the hub/rotor area.
    3. Insert two M10 x 1.5 bolts or jack screws into the threaded holes of the rotor.
    4. Tighten both bolts evenly to force the rotor from the hub.
