Rear Disc Brake Pads Replacement

Removal Procedure

Warning:
Refer to Brake Dust Warning Brake Dust Warning.


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 Service and Repair.

5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.





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 caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin bolt. DO NOT allow the open end wrench to come in contact with the brake caliper. Allowing the open end wrench to come in contact with the brake caliper will cause a pulsation when the brakes are applied.

6. Using a backup wrench to hold the brake caliper guide pin stationary, remove the brake caliper guide pin bolts (1).

Caution:
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.

7. Remove the brake caliper from the brake caliper bracket and support with heavy mechanics wire or equivalent.





8. Remove the brake caliper bracket bolts (1).





9. Remove the brake caliper bracket assembly (1).





10. Remove the outer brake pad (1).

Note:
The inner brake pad is equipped with the wear sensor.

11. Remove the inner brake pad (2).





12. Remove the upper and lower brake pad springs (1).

13. If installing new brake pads, discard the springs.

Installation Procedure





Note:
If installing new brake pads, install new springs.

1. Install new brake pad springs (1).





2. Install the outer brake pad (1).

Note:
The inner brake pad is equipped with the wear sensor.

3. Install the inner brake pad (2).

4. Prepare the brake caliper bracket bolts and the bracket threaded holes for assembly:

* Thoroughly clean the residue from the bolt threads with denatured alcohol or equivalent and allow to dry.

* Thoroughly clean the residue from the threaded holes with denatured alcohol or equivalent and allow to dry.

* Apply threadlocker to 2/3 of the threaded length of the caliper bracket bolts. Refer to Adhesives, Fluids, Lubricants, and Sealers Fluid Type Specifications

* Ensure there are no gaps in the threadlocker along the length of the filled area of the bolts.

* Allow the threadlocker to cure approximately 10 minutes before installation.





5. Install the brake caliper bracket assembly (1).





Caution:
Refer to Fastener Caution Fastener Caution.

6. Install the brake caliper bracket bolts (1) and tighten to 100 Nm (74 lb ft) + 60 degrees).

7. Using an appropriate brake caliper piston spanner tool, slowly rotate the brake caliper piston clockwise while applying inward pressure to the brake caliper piston until the piston is fully seated in the brake caliper housing.

8. Ensure the notches in the brake caliper piston align correctly with the pins on the inner disc brake pad.





9. Install the brake caliper to the brake caliper bracket.

10. Using a backup wrench to hold the brake caliper guide pin stationary, install the brake caliper guide pin bolts (1) and tighten to 27 Nm (20 lb ft).

11. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation Service and Repair.

12. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.

13. Slowly release the brake pedal.

14. Wait 15 seconds, then repeat steps 10-11 until a firm brake pedal is obtained. This will properly seat the brake caliper piston and brake pads.

15. Fill the master cylinder reservoir. Refer to Master Cylinder Reservoir Filling Master Cylinder Reservoir Filling.

16. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing Procedures.
