Backing Plate: Service and Repair

NOTE: Before proceeding with this procedure, review applicable Service Precautions.

REMOVAL






1. Using a brake pedal holding tool as shown, depress the brake pedal past its first one inch of travel and hold it in this position. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to drain out of the master cylinder reservoir.
2. Raise the vehicle.
3. Remove the rear tire and wheel assembly from the vehicle.






4. Disconnect the rear brake flex hose from the wheel cylinder.
5. Remove the rear brake drum.






6. Remove the dust cap from the rear hub and bearing.







7. Remove the nut holding the rear hub and bearing to the spindle. Remove the hub and bearing from the spindle.
8. Remove the rear brake shoes from the brake support plate.
9. Remove the parking brake actuator lever from the parking brake cable.






10. Position a 1/2 inch wrench over the retainer fingers on the end of the parking brake cable. Compress the cable housing retaining fingers with the wrench, then pull the cable housing out of the support plate. Remove the wrench as the parking brake cable retainer is freed from the mounting hole in the brake support plate.
11. Remove the 4 brake support plate mounting bolts and washers. Separate brake support plate from rear suspension knuckle.
12. Remove the brake wheel cylinder attaching bolts.
13. Remove the brake wheel cylinder from the brake support plate.

INSTALLATION

NOTE: When installing wheel cylinder on brake support plate, be sure it is positioned squarely (horizontal) to the brake support plate.

2. Install the wheel cylinder onto brake support plate. Tighten the attaching bolts to a torque of 13 Nm (115 inch lbs.).
3. Install the brake support plate and gasket on rear suspension knuckle. Tighten the support plate mounting bolts to a torque of 75 Nm (55 ft. lbs.).
