Front Disc Brake Pads Replacement

Removal Procedure

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

  1. Inspect the fluid level in the brake master cylinder reservoir.
  2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed before proceeding.
  3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
  4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
  5. Remove the tyre and wheel assembly. Refer to Tyre and Wheel Removal and Installation .

    6. 1873943

    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.

  6. Using a backup wrench to hold the brake calliper guide pin stationary, remove the lower brake calliper guide pin bolt (1).

    7. 1873944

    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.

  7. Pivot the brake calliper (1) upward.
  8. Place a block of wood or an old brake pad against the brake calliper pistons.
  9. Using a brake pad spreader tool or equivalent, fully seat the calliper pistons in the calliper bores.

    10. 1873962

    Note: Note the location of the brake pad wear sensor for correct installation.

  10. Remove the inner brake pad (1) and the outer brake pad (2).

    11. 1873964
  11. Remove the upper and lower brake pad springs (1).
  12. If installing new brake pads, discard the springs.

  4. Using a backup wrench to hold the brake calliper guide pin stationary, install the lower brake calliper guide pin bolt (1) and tighten to 44 N·m (32 lb ft).
  5. Install the tyre and wheel assembly. Refer to Tyre and Wheel Removal and Installation .
  6. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
  7. Slowly release the brake pedal.
  8. Wait 15 seconds, then repeat steps 6-7 until a firm brake pedal is obtained. This will properly seat the brake calliper pistons and brake pads.
  9. Fill the master cylinder reservoir to the proper level. Refer to Master Cylinder Reservoir Filling .
  10. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing .
