To service and repair the 12 1/8 inch rear brake shoe, raise and support the vehicle and remove the wheel and tire assembly. Then, remove the clip nuts that hold the brake drum to the wheel studs and remove the brake drum. Using a vacuum, clean the brake parts to remove brake lining dust. Disconnect the adjusting lever return spring from the lever. Next, remove the lever, with the return spring from the lever pivot pin. Remove the adjuster lever from the adjuster cable assembly, then remove the shoe-to-shoe upper spring and the shoe hold-down springs. To remove the brake shoes, first disconnect the parking brake cable. Next, remove the shoe-to-shoe lower spring and adjuster assembly. Before installation, the pivot screw and the adjusting nut must have left-hand thread on the left side brake and right hand thread on the right side brake. Ensure that the appropriate adjusting nuts are used on the correct side of the vehicle. Apply Mopar high-temperature grease, or equivalent, to the contact pads on the support plate. Put together the adjuster, lower spring, and both brake shoes. Position the fully assembled assembly on the support plate, with the primary shoe towards the front of the vehicle and the secondary shoe towards the rear. Make sure the seat of the hold-down pins is in the support plate and the springs are hooked to install the brake shoe hold-down springs and pins. Position the parking brake cable through the parking brake cable guide spring to the parking brake lever and make sure the cable end is lodged properly in the lever. Firstly, install the upper spring, then position the return spring of the adjuster lever on its pivot. Finally, install the adjuster lever. Attach the adjuster cable to the adjuster lever, ensuring the cable is properly routed, and finally adjust the brake shoes to the drum using a brake gauge.
