To remove the 1500 model rear brake shoes, first loosen the rear wheel lug nuts, raise the vehicle, and remove the wheels. Then, remove the brake caliper, mounting bracket, and brake disc. After washing the brake assembly with brake system cleaner, remove the clip securing the bottom of the shoe and slide the shoe up and off of the actuator. Lift one end of the shoe over the axle flange, work the shoe over the flange, and remove it. Before installing the new shoe, turn the adjuster screw star wheel in and ensure the slots in the adjusting screw and the tappet are parallel with the backing plate. To install the shoe, reverse the removal procedure, making sure the ends of the shoe seat properly in the slots in the adjuster screw and tappet. When installing the new shoe and lining assembly, turn the adjuster screw until the shoe lining just drags on the braking surface inside the disc. Then remove the disc and back off the adjuster screw until the shoe lining doesn't drag when the disc is installed and turned. The actual clearance between the lining surface of the shoe and the braking surface inside the disc should be 0.026 inches. For the 2500/3500 model, follow the same initial steps to remove the brake shoes, but also remove the hold-down clip from each parking brake shoe and unhook the return springs from the top and bottom of each shoe. Installation of the new shoes is the reverse of the removal procedure, with the same adjustment steps for the shoe lining clearance. Be sure to tighten all bolts and lug nuts to the torque specifications.

To remove and install rear brake shoes, first loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Release the parking brake and remove the wheel. If the brake drum has never been removed, remove the drum retainer clip. Wash the brake assembly with brake system cleaner and allow it to drip dry into a pan. Unhook the lower spring and remove it, then remove the upper spring from the adjuster lever. Remove the adjuster lever, star-wheel assembly, front brake shoe, and rear shoe retainer. Pry open the clip to disconnect the parking brake lever from the rear shoe. To install, lubricate the backing plate contact points and crimp the clip to attach the new rear shoe to the parking brake lever. Install the pin through the backing plate and the rear shoe, then install the spring and the retainer to the pin. Use a special tool to compress the spring and engage the retainer, and perform the same procedure on the front brake shoe. Clean and lubricate the star-wheel adjuster, then install the star-wheel assembly with the star to the front and the adjuster lever. Install the upper spring, hooking it into the adjuster, and the lower spring. Adjust the star wheel to give a very light drag when the brake drum is turned. Install the brake drum on the axle flange, pump the brake pedal, and turn the drum to listen for the sound of the shoes rubbing. If they are, turn the adjuster star wheel until the shoes stop rubbing. Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the torque specifications. Make a number of forward and reverse stops to seat the shoes to the drum and to actuate the auto-adjusting mechanism. Check the operation of the parking brake and adjust if necessary, and check the operation of the brakes carefully before driving the vehicle.

To adjust the rear brake shoes, follow these steps: Clean and lubricate the star-wheel adjuster. Install the star-wheel assembly with the star to the front and the adjuster lever. Install the upper spring, hooking it into the adjuster, and the lower spring. Adjust the star wheel to give a very light drag when the brake drum is turned. Install the brake drum on the axle flange.
