To service and repair the backing plate, first ensure safety by isolating the master cylinder from the brake hydraulic system by using a brake pedal holding tool to depress the brake pedal past one inch (25 mm) and hold it in that position. Next, raise and support the vehicle, then remove the three wheel mounting nuts followed by the tire and wheel assembly. Access the drum brake shoes and remove them from the support plate. Use a 10 mm box wrench to compress the retainer fingers on the end of the parking brake cable housing, then pull the cable housing out of the support plate. Disconnect the brake tube at the wheel cylinder and remove the wheel cylinder attaching screws to take the wheel cylinder out of the support plate. If a wheel speed sensor is present, remove the screw fastening the sensor head in the rear of the hub and bearing and take the sensor head out. Finally, remove the four bolts securing the hub and bearing, support plate, and spacer to the knuckle, then take the hub and bearing, support plate, and spacer out as an assembly from the knuckle, separating the spacer and hub and bearing from the support plate afterward.
