Removal Procedure

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

    Danger: Do not use a service jack in locations other than those specified to lift this vehicle. Lifting the vehicle with a jack in those other locations could cause the vehicle to slip off the jack and roll; this could cause injury or death.

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
  2. Remove the tyre and wheel assembly. Refer to Tyre and Wheel Removal and Installation .

  3. 1385046

    Note: 

       • DO NOT use any air tools to remove or install the guide pin bolts. Use hand tools ONLY
       • Install an open end wrench to hold the calliper guide pin in line with the brake calliper while removing or installing the calliper guide pin bolt. DO NOT allow the open end wrench to come in contact with the brake calliper. Allowing the open end wrench to come in contact with the brake calliper will cause a pulsation when the brakes are applied.

  4. Using a backup wrench to hold the brake calliper guide pin (1) stationary, remove the brake calliper guide pin bolts (2).
  5. Caution: Support the brake calliper 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 calliper in this manner will cause the flexible brake hose to bear the weight of the calliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.

  6. Remove the brake calliper and support with heavy mechanics wire or equivalent.
