To facilitate servicing and repair of the backing plate, remove the wheel and tire assemblies, then remove the brake drums. Following that, as described in the Transmission and Drivetrain section, withdraw the axle shaft then remove the brake shoes and hardware to access the parking brake cable. Remove the brake line from the wheel cylinder, detach the cable from the support plate, and remove the parking brake cylinder. After that, the bolts connecting the support plate to the axle were removed and the support plate was taken out. To install, run a thin bead of silicone sealer about the axle mounting surface of the support plate and install it onto the axle flange and tighten the attaching bolts to 47 - 68 Nm (35 - 50 ft. lbs.). After that, install the wheel cylinder on the new support plate using a thin bead of silicone sealer around the wheel cylinder mounting surface. Install the parking brake cable into the support plate, followed by the brake shoes and hardware. Using a brake gauge, reinstall the axle shaft and adjust the brake shoes to the drum. Finally, install the brake drums, fill and bleed the brake system, and reinstall the wheel and tire assemblies before lowering the vehicle.
