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 adjusting wheel. Put the car in reverse and, while backing up, firmly apply the brakes. This will allow the self-adjusters to complete the adjustment.
REMOVAL & INSTALLATION
See Figures 1 through 14
- Raise the car and support it on jackstands.
- Slacken the parking brake cable.
- Remove the rear wheel and brake drum. The front wheel and 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, hold-down pins and springs, and actuator assembly.
Special tools available from auto supply stores will ease removal of the spring and anchor pin, but the job may still be done with common hand tools.
- On the rear wheels, disconnect the adjusting mechanism and spring, and remove the primary shoe. The primary shoe has a shorter lining than the secondary and is mounted at the front of the wheel.
- 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 cylinders for seal condition and leaking.
- Repack the 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, 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 to the secondary shoe when correctly installed.
- To install, reverse the removal procedure. When completed, adjust the brake shoes, as described earlier in this section.
Maintenance procedures for the metallic lining option are the same as those for standard linings. Do not substitute these linings in standard drums, unless they have been honed to a 20 micro-inch finish and equipped with special heat-resistant springs.
