Removal Procedure

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


    Object Number: 1212960 Size: SH

    Notice: Support the brake caliper 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 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.

  1. Remove the brake caliper from the brake caliper mounting bracket and support the brake caliper with heavy mechanic's wire (1), or equivalent. Do NOT disconnect the hydraulic brake flexible hose from the caliper. Refer to Front Brake Caliper Replacement .
  2. Remove the brake pads (2) from the brake caliper bracket.

    3. Object Number: 891434 Size: SH
  3. Remove the brake pad retainers (2) from the brake caliper bracket.
  4. If reusing the bracket, thoroughly clean the pad hardware mating surfaces (1) of the caliper bracket, of any debris and corrosion.
  5. Inspect the disc brake pad retainers (2) for the following:
    6. • Bent mounting tabs
    • Excessive corrosion
    • Looseness at the brake caliper mounting bracket
    • Looseness at the disc brake pads
  6. If any of the conditions listed are found, the disc brake pad retainers require replacement.

    7. Object Number: 890739 Size: SH
  7. Remove the brake caliper mounting bracket bolts (1).
  8. Remove the brake caliper bracket from the steering knuckle.

    9. Object Number: 1212693 Size: SH
  9. Inspect the caliper bracket (5). If the brake caliper bracket (5) is bent, cracked, or damaged, it requires replacement.
  10. Inspect the brake caliper guide pins (2) for freedom of movement, and inspect the condition of the guide pin boots (4). Move the brake caliper guide pins (2) inboard and outboard within the brake caliper bracket (5), without disengaging the slides from the boots, and observe for the following:
    11. • Restricted caliper guide pin movement
    • Looseness in the brake caliper mounting bracket
    • Seized or binding caliper guide pins
    • Split or torn boots
  11. If any of the conditions listed are found, the brake caliper guide pins (2) and/or boots (4) require replacement.

Installation Procedure

    Notice: This is a self-retaining fastener joint that does not require thread locking compounds. Do not attempt to clean the threads with a standard tap. If a standard tap is used, damage to the joint threads will occur.


    Object Number: 890739 Size: SH
  1. Install the brake caliper mounting bracket to the steering knuckle.

    2. Notice: Refer to Fastener Notice in the Preface section.

  2. Install the brake caliper mounting bracket bolts (1).

    3. Tighten
    Tighten the bolts to 130 N·m (96 lb ft).


    Object Number: 891434 Size: SH
  3. Apply a very thin coating of high temperature silicone brake lubricant to the pad hardware mating surfaces (1) of the caliper bracket only.
  4. Clean the brake pad mating surfaces of the brake pad retainers (2).
  5. Install the brake pad retainers (2) to the brake caliper bracket.

    6. Object Number: 1212960 Size: SH

    Important: The wear sensor equipped disc brake pad must be mounted inboard of the rotor with the leading edge of the sensor facing the brake rotor during forward wheel rotation, or at the top of the pad when installed in vehicle position.

  6. Install the brake pads (2) to the brake caliper bracket.
  7. Remove the support (1) and reposition the brake caliper over the brake pads and to the mounting bracket. Refer to Front Brake Caliper Replacement .
