Back off parking brake adjuster. See Figure . Using hammer and small punch, bend knockout slug (where access hole plug will be installed) on each backing plate inward for access to parking brake lever. Insert punch or screwdriver through hole. Press inward to push parking brake lever off of its stop. This allows the shoes to retract slightly.
Apply a small amount of penetrating oil around pilot hole at center of drum to break corrosion seal between drum and wheel stud flange. Remove drums. Using pliers, remove knockout slug on each backing plate. Insert rubber plug into access hole to prevent contamination from entering brake assembly.
Ensure lever stop on parking brake lever is against edge of brake shoe web. See Figure . If parking brake cable is holding lever stop off of edge of shoe web, loosen parking brake cable adjuster. Measure inner diameter of brake drums. At each brake assembly, turn star wheel on adjusting screw assembly until brake shoe diameter is .050" (1.27 mm) less than inner diameter of drum.
Install drums and wheels, aligning marks made during removal. Tighten wheel lug nuts to specification. See TORQUE SPECIFICATIONS. Lower vehicle. Firmly apply and release service brakes 30-35 times using normal braking force, pausing about one second between brake applications. Adjust parking brake (if necessary).
