First, lift and support the vehicle on adequate safety stands; remove the tire and wheel. Mount the pin to the park brake lever and then take out rear Brake Drum, rear brake shoes, rear Wheel Cylinder, and rear brake anchor, pin. After this, brave yourself and remove the rear Brake Backing Plate retaining bolts and washers and remove the rear Brake Backing Plate from the vehicle. Install the new rear Brake Backing Plate and fasten it with retaining bolts and washers and tighten up to 140 nm (104 ft. Lbs.). Replace the rear Wheel Cylinder and rear brakes shoes, than the pin from the park brake lever are removed. Change the rear brakes, release the brake system, and replace the tire and wheel. If necessary, decrease the park-brake, and then take away the safety stands and put the car down.

To service the disc Brake Dust Shields first put the vehicle on stands and then remove the tire wheel assembly brake caliper hub and rotor. Separate the Wheel Speed Sensor electrical connector and take off the rosebud clip from the frame while keeping note of the sensor wire clip position at the shock tower which requires reinstalling at 45 degrees to the vehicle's center line. Disconnect bolt 9 and washer 15 holding the sensor wire clip at the shock tower and then take off rosebud clip from upper Control Arm at 7300 gvw c6a. Take out the bolt and nut which secure the sensor wire clip at the upper Ball Joint assembly (parts 5,12). The Wheel Speed Sensor stays fixed to its position on the dust shields since it needs only a nut/bolt placement at the top hole rather than removal. Take out the dust shield assembly and its face seal by first removing all dust shield bolts then the Wheel Speed Sensor and gasket. Carefully remove any dirt from both the dust shield gasket region and the knuckle. Position the dust shield gasket on the knuckle spindle first before installing the Wheel Speed Sensor and dust shield set. Secure the dust shield mounting bolts using 26 nm torque which is equivalent to 19 ft. Lbs. Place the sensor wire clip back on top of Ball Joint (5,12), then tighten both wheel sensor wire clip nut (4,11) and bolt (7,14) to 17 nm (13 ft. Lbs). Only for the 7300 lb. Gvw (C6A) models install the wire clip to the upper Control Arm. Made to meet the shock tower sensor wire clip at a 45-degree orientation to the car's center axis and fasten it with the bolt at the shock tower while tightening to 15 nm (11 ft. Lbs.). Connect the Wheel Speed Sensor connector to the inner frame rail and attach its rosebud clip before joining it to the vehicle harness. Put back all hardware elements before testing the vehicle beyond 32 km/h (20 mph) speed. Use special monitoring equipment to erase diagnostic problems and to check wheel movement accuracy during testing.
