Brake Caliper Replacement-Rear

REMOVAL PROCEDURE
1. Remove one-third of the brake fluid from the master cylinder.
2. Raise and suitably support the vehicle.
3. Mark the relationship of the wheel to the hub and bearing.
4. Remove the tires and the wheel.
Install two wheel nuts in order to retain the rotor.





5. Push the piston (7) onto the caliper bore (2) in order to provide clearance between the linings and the rotor. Complete the following steps:
- Install a large C-clamp over the top of the caliper housing (15) and against the back of the outboard pad (9).
- Slowly tighten the C-clamp until the piston (7) is pushed into the caliper bore (2) enough in order to slide the caliper (15) off the rotor. Do not overtighten the C-clamp. Overtightening will deform the outboard shoe (9).

6. Remove the hose bolt attaching the inlet fitting.
7. Plug the openings in the caliper housing (15) and the pipe in order to prevent brake fluid loss and contamination.
8. Remove the caliper bolts (1 and 3).

NOTICE: Do not allow calipers to hang from the flexible hoses. Doing so can damage the hoses.





9. Remove the caliper housing (3) from the rotor (4) and the caliper bracket (1).
10. Inspect the piston boots for the following conditions:
- Cuts
- Tears
- Deterioration
Replace the piston boots if damage exists.
Refer to Brake Caliper Overhaul-Rear.

11. Inspect the caliper bracket boots for the following conditions:
- Cuts
- Tears
- Deterioration
Replace the caliper bracket boots if damage exists.

12. Inspect the caliper bolts (2) for corrosion or damage. If corrosion is found, use new parts, including bushings, when installing caliper. Do not attempt to polish away corrosion.


INSTALLATION PROCEDURE





1. Install the caliper (3) over the rotor (4) and the caliper bracket (1). Ensure that the bushings are in place.





2. Lubricate the caliper bolts (1 and 3). Use silicone grease. Do not lubricate the threads.
3. Lubricate the two rubber boots (13 and 4) in the caliper bracket (12). Use silicone grease.

NOTICE: Refer to Fastener Notice in Service Precautions.

4. Install the caliper bolts (1 and 3). Use a screwdriver in order to push the boot over the shoulder of the caliper bolt. Ensure that the boot is securely in the groove of the caliper bolt.
- Tighten the caliper bolts (1 and 3) to 43 Nm (32 lb ft).

IMPORTANT: Replace the copper gaskets.

5. Install the brake hose bolt.
- Tighten the brake hose bolt to 44 Nm (32 lb ft).

6. Remove the wheel nuts securing the rotor to the hub and bearing.
7. Install the tires and the wheels.
Align the previous marks on the wheel and the hub and bearing.
8. Lower the vehicle.
9. Fill the master cylinder to the proper level with clean brake fluid.
10. Bleed the entire brake system.
11. Apply the brake pedal approximately three times after bleeding, to seat the brake pads against the rotor.
12. Inspect the hydraulic brake system for brake fluid leaks.
