Install the brake adjuster screw with the slot in the head of the brake adjuster screw toward the primary rear brake shoe and lining.
Install the lower brake shoe retracting spring, adjusting lever return spring, adjusting lever assembly (part of brake shoe adjusting lever), and connect the parking brake lever to the adjusting lever.
NOTE: Install the brake adjuster screws in the same locations from which they were removed. Interchanging them from one side of the vehicle to the other will cause the rear brake shoes and linings to retract rather than expand each time the automatic adjusting mechanism is operated. To prevent incorrect installation, the socket end of each adjusting screw is stamped with an R or L to indicate their installation on the right or left side of the vehicle. The adjusting pivot nuts can be distinguished by the number of lines machined around the body of the nut. Two lines indicate a right-hand nut; one line indicates a left-hand nut.
Position the brake shoe adjusting lever cable in the cable guide and install the cable anchor fitting on the anchor pin.
Install the parking brake lever in the anchor pin and washer and secure with the retaining nut behind the brake backing plate.
Adjust the brakes before installing the brake drums.
