Brake Pads Replacement - Rear

Caution: Refer to Brake Dust Caution.

Caution: Refer to Brake Fluid Irritant Caution.

Removal Procedure
1. Inspect the fluid level in the brake master cylinder auxiliary reservoir.
2. If the brake fluid level is midway between the full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
3. If the brake fluid level is higher than midway between the 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 in General Information.
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
6. Install and firmly hand tighten 2 wheel nuts to opposite wheel studs in order to retain the rotor to the hub.





7. Install a large C-clamp, over the body of the brake caliper with the C-clamp ends against the rear of the caliper body and against the outer brake pad.
8. Tighten the C-clamp just enough to compress the caliper piston 1 mm (0.039 in) of travel only.

Notice: When using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake mechanism, do not exceed more than 1 mm (0.039 in) of piston travel. Exceeding this amount of piston travel will cause damage to the internal adjusting mechanism and/or the integral park brake mechanism.

9. Remove the C-clamp from the caliper.





10. While using a wrench on the flats of the caliper guide pins (1), remove the brake caliper guide pin bolts (2).
11. Without disconnecting the hydraulic brake flexible hose, remove the caliper from the mounting bracket and secure the caliper with heavy mechanics wire (1), or equivalent.

Notice: Support 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.





12. Remove the brake pads from the caliper mounting bracket.
13. Remove the brake pad retainers (1) from the caliper bracket.
14. Thoroughly clean the brake pad hardware mating surfaces of the caliper bracket (2), of any debris and corrosion.
15. Inspect the brake caliper guide pins for freedom of movement, and inspect the condition of the guide pin boots. Move the guide pins inboard and outboard within the bracket bores, without disengaging the slides from the boots, and observe for the following:
^ Restricted caliper guide pin movement
^ Looseness in the brake caliper mounting bracket
^ Seized or binding caliper guide pins
^ Split or torn boots
16. If any of the conditions listed are found, the brake caliper guide pins and/or boots require replacement.





17. Using a spanner wrench type caliper piston installer, fully retract the piston into the caliper bore.

Installation Procedure





1. Apply a very thin coating of high temperature silicone brake lubricant to the pad hardware mating surfaces of the caliper bracket (2) only.
2. Install the brake pad retainers (1) to the brake caliper bracket.
3. Install the brake pads to the caliper bracket.

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 bottom of the pad when installed in vehicle position.

4. Remove the support, and install the caliper into position over the disc brake pads and to the caliper mounting bracket.





5. While using a wrench on the flats of the caliper guide pins (1), install the brake caliper guide pin bolts (2).
Tighten the bolts to 34 Nm (25 lb ft).

Notice: Refer to Fastener Notice.

6. Remove the wheel nuts retaining the brake rotor to the hub.
7. Install the tire and wheel assembly.
8. Lower the vehicle.
9. With the engine OFF, gradually apply the brake pedal approximately 2/3 of its travel distance.
10. Slowly release the brake pedal.
11. Wait 15 seconds, then gradually apply the brake pedal approximately 2/3 of its travel distance again until a firm brake pedal apply is obtained. This will properly seat the brake caliper pistons and brake pads.
12. Fill the master cylinder auxiliary reservoir to the proper level. Refer to Master Cylinder Reservoir Filling. Master Cylinder Reservoir Filling
13. Burnish the pads and rotors. Refer to Burnishing Pads and Rotors. Burnishing Pads and Rotors
