Rotate the star wheel adjuster until a slight drag is felt between the shoes and drum, then back off 1 1 / 4 turns on the adjuster. Backing the car and firmly braking will allow the self-adjusters to complete the adjustment.
REMOVAL & INSTALLATION
- Raise the car and support it on jackstands.
- Slacken the parking brake cable.
- Remove the rear wheel and brake drum. The front wheel and brake drum may be removed as a unit by removing the spindle nut and cotter pin.
- Free the brake shoe return springs, actuator pull-back spring, and link hold-down-pins and springs, and the actuator assembly.
Special tools available from auto supply stores will ease spring and anchor pin removal, but the job may still be done with common hand tools.
- Remove the primary brake shoe and lining. On rear wheels, disconnect the adjusting mechanism and spring from the primary shoe.
- On rear wheels, disconnect the parking brake lever from the secondary shoe and remove the shoe. (Front wheel shoes may be removed together.)
- Clean and inspect all brake parts.
- Check the wheel cylinder for seal condition and leaking.
- Repack wheel bearings and replace the seals.
- Inspect the replacement shoes for nicks or burrs, lubricate the backing plate contact points, brake cable and levers, and adjusting screws, and then assemble.
- Make sure that the right- and left-hand adjusting screws are not mixed. You can prevent this by working on one side at a time. This will also provide you with a reference for reassembly. The star wheel should be nearest the secondary shoe when correctly installed.
- Reverse the removal procedure for assembly. When completed, make an initial adjustment as previously described.
Maintenance procedures for the metallic lining option are the same as those for standard linings. Do not substitute these linings in standard drums, unless the drums have been honed to a 20-micro-inch finish and the shoes equipped with special heat-resistant springs.
