Removal (Front)

WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the brake fluid level in the brake master cylinder reservoir.
  2. If the brake fluid is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
  3. If the brake fluid level is higher than midway between thew maximum-full point and the minimum allowable level, using a appropriate tool, remove the brake fluid to the midway point before proceeding.
  4. Raise the vehicle. Remove the tire and wheel assembly.
  5. Compress the front brake caliper piston:
    1. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard brake pad. See Fig 1 .
    2. Slowly tighten the C-clamp until the piston pushes into the brake caliper enough to slide the brake caliper off the rotor.
    3. Remove the C-clamp from the brake caliper.
  6. Remove the mounting bolts from the brake caliper mounting bracket. See Figure .
    7. NOTE: When performing the following service procedure, the front brake caliper assembly and the front brake caliper mounting bracket can be removed as an assembly.
  7. Remove the brake caliper and mounting bracket assembly. See BRAKE CALIPER BRACKET  .
  8. Remove the retaining clips from the brake rotor. See Fig 2 .
    9. CAUTION: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the rotor and flange with the Wheel Hub Cleaning Kit (J-42450). Failure to do this may result in increased lateral runout of the rotor and brake pulsation.
    NOTE: If the brake rotor is not going to be replaced but just removed from the front hub, mark the relationship of the brake rotor and a wheel stud.
  9. Remove the front brake rotor from the wheel hub.
  10. Using the Wheel Hub Cleaning Kit, clean the brake rotor contact area on the front hub. See Fig 3 .
