Removal & Installation
- Before servicing the vehicle, refer to the Precautions Section.
- Inspect the fluid level in the brake master cylinder reservoir.
- If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
- 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.
- Raise and support the vehicle.
- Remove the tire and wheel assembly.
- Unclamp the Wheel Speed Sensor (WSS) harness from the lower control arm.
Remove both upper and lower caliper bolts from the caliper.
WARNINGSupport 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.
- Pull the caliper straight off of the bracket and secure out of the way with heavy mechanic-s wire. DO NOT disconnect the hydraulic brake flexible hose from the caliper.
Remove the inboard and outboard pads from the brake caliper bracket.
- Inspect the brake caliper bracket guide boot assembly for condition.
- Clean the brake pad hardware mating surfaces on the caliper bracket of any debris or corrosion.
- Inspect the brake pad retainer clips for condition and replace, if necessary.
- Inspect the piston boot for condition. Replace if damaged.
- Retract the brake caliper piston into the brake caliper bore. Use a suitable spanner type wrench and turn the piston clockwise until it bottoms out fully in the brake caliper (Mac® Tools DBC 25 C 2500 MA Disc Brake Caliper Tool Set, or equivalent).
- Align the indents on the piston face to match the pin on the back of the inboard brake pads.
- Install the brake pad retainers into the brake caliper bracket.
- Install the inboard and outboard brake pads into the brake caliper bracket insuring that the pad with the metallic wear sensor is placed on the inboard side of the bracket.
- Slide the caliper onto the bracket insuring that the bracket guide boots are not damaged.
- Insert the brake caliper bolts. Tighten the brake caliper bolts to 25 ft. lbs. (34 Nm).
- Re-clamp the WSS harness onto the lower control arm.
- Install the tire and wheel assembly.
- Lower the vehicle.
- With the engine OFF, gradually apply the brake pedal to approximately 2 / 3 of its travel distance.
- Slowly release the brake pedal.
- Wait 15 seconds, then repeat steps 10-11 until a firm brake pedal apply is obtained. This will properly seat the brake caliper pistons and brake pads.
- Fill the brake master cylinder reservoir to the proper level.
