###### Front

1. Raise and support the front of the vehicle on jackstands, then remove the wheels.
2. Remove the bottom guide pin from the caliper and swing the caliper cylinder body upward as hang by a wire.
3. Remove the brake pad retainers and the pads.

   To install:

4. Compress the piston of the disc brake caliper.
5. Install the brake pads and caliper assembly. Torque the guide pin to 23-30 ft. lbs. (31-41 Nm).
6. Install the wheels.
7. Apply the brakes a few times to seat the pads. Check the master cylinder and add fluid if necessary. Bleed the brakes, if necessary.

###### Rear

NOTE: Do not press the piston into the bore as performed on the front disc brakes. Due to the parking brake mechanism, the caliper piston must be turned into the bore using a special tool.

1. Raise and support the vehicle safely.
2. Remove the rear wheels.
3. Release the parking brake and remove the cable bracket bolt.
4. Remove the pin bolts and lift off the caliper body.
5. Pull out the pad springs and then remove the pads and shims.

   To install:

6. Clean the piston end of the caliper body and the area around the pin holes. Be careful not to get oil on the rotor.
7. Using the proper tool, carefully turn the piston clockwise back into the caliper body. Take care not to damage the piston boot.
8. Coat the pad contact area on the mounting support with a silicone based grease.
9. Install the pads, shims and the pad springs. Always use new shims.
10. Position the caliper body in the mounting support and tighten the pin bolts to 28-38 ft. lbs. (38-52 Nm).
11. Mount the wheels, lower the vehicle and bleed the system if necessary.

2. Remove the clip from the pad pins and then remove the pins.
3. Remove the cross spring from the disc caliper.
4. Pull out the outer disc brake pad and insert it temporarily between the lower piston and disc rotor.
5. Push the upper piston back using a suitable tool and insert the new brake pad so it contacts the upper piston only.
6. Pull the old brake pad from the lower piston.
7. Push the lower piston back using a suitable tool.

NOTE: The parking brake assembly is located inside the disc rotor and has no affect on the rear disc caliper.

1. Raise and support the vehicle safely.
2. Remove the rear wheels.
3. Remove the clip from the pad pins and then remove the pins.
4. Remove the cross spring from the disc caliper.
5. Pull the outer disc brake pad from the disc caliper.
6. Push back the outer piston using a suitable tool and install a new disc brake pad with shims.
