Note: Any time the brake drums are removed for brake service, the braking surface diameter should be checked with a suitable brake drum micrometer at several points to determine if they are within the safe oversize limit stamped on the brake drum outer surface. If the braking surface diameter exceeds specifications, the drum must be replaced. If the braking surface diameter is within specifications, drums should be cleaned and inspected for cracks, scores, deep grooves, taper, out of round and heat spotting. If drums are cracked or heat spotted, they must be replaced. Minor scores should be removed with sandpaper. Grooves and large scores can only be removed by machining with special equipment, as long as the braking surface is within specifications stamped on brake drum outer surface. Any brake drum sufficiently out of round to cause vehicle vibration or noise while braking or showing taper should also be machined, removing only enough stock to true up the brake drum.

After a brake drum is machined, wipe the braking surface diameter with a denatured alcohol soaked cloth. If one brake drum is machined, the other should also be machined to the same diameter to maintain equal braking forces.
Note: You should consider replacing the drums, even though on above you have to have the measured and turned if worn. They are only about $35.00 at Auto Zone and it is well worth it. Also, once you get everything apart, it is also well worth replacing both wheel cylinders, item 26. The cost to rebuild them doesn't equal the $10.00 they cost at AZ. They need to be replaced.


1.Raise and support rear of vehicle, then remove tire and wheel assembly.
2.Remove brake drum. If brake lining is dragging on brake drum, back off brake adjustment by rotating. adjustment screw. Refer to individual car chapter for procedure. If brake drum is rusted or corroded to axle flange and cannot be removed, lightly tap axle flange to drum mounting surface with a suitable hammer.
3.Using brake spring pliers or equivalent, unhook primary and secondary return springs, Fig. 1. Observe location of brake parts being removed to aid during installation.
4.Remove brake hold-down springs with suitable tool.
5.Lift actuating lever, then unhook actuating link from anchor pin and remove.
6.Remove actuating lever(s) and return spring.
7.Spread shoes apart and remove parking brake strut and spring.
8.Disconnect parking brake cable from lever, then remove brake shoes from backing plate.
9.Separate brake shoes by removing adjusting screw and spring, then unhook parking brake lever from shoe assembly.
10.Clean dirt from brake drum, backing plate and all other components. Do not use compressed air or dry brush to clean brake parts. Many brake parts contain asbestos fibers which, if inhaled, can cause serious injury. Clean brake parts with a water soaked rag or a suitable vacuum cleaner to minimize airborne dust.


1.Lubricate parking brake lever fulcrum with suitable brake lube, then attach lever to brake shoe. Ensure lever operates smoothly.
2.Connect brake shoes with adjusting screw spring, then position adjusting screw. Ensure adjusting screw star wheel does not contact adjusting screw spring after installation and also ensure righthand thread adjusting screw is installed on left side of vehicle and lefthand thread adjusting screw is installed on right side of vehicle. When brake shoe installation is completed, ensure starwheel lines up with adjusting hole in backing plate.
3.Lightly lubricate backing plate shoe contact surfaces with suitable brake lube, then the area where parking brake cable contacts backing plate.
4.Install brake shoes on backing plate while engaging wheel cylinder links (if equipped) with shoe webbing. Connect parking brake cable to parking brake lever. The primary shoe (short lining) faces towards front of vehicle.
5.Install actuating levers, actuating link and return spring, Fig. 1 .
6.Install hold-down springs with suitable tool.
7.Install primary and secondary shoe return springs using brake spring pliers or equivalent.
8.Using suitable brake drum to shoe gauge, measure brake drum inside diameter. Adjust brake shoes to dimension obtained on outside portion of gauge.
9.Install brake drum, wheel and tire assembly.
10.If any hydraulic connections have been opened, bleed brake system.
11.Adjust parking brake. Refer to individual car chapters for procedures.
12.Inspect all hydraulic lines and connections for leakage and repair as necessary.
13.Check master cylinder fluid level and replenish as necessary.
14.Check brake pedal for proper feel and return.
15.Lower vehicle and road test. Do not severely apply brakes immediately after installation of new brake linings or permanent damage may occur to linings, and/or brake drums may become scored. Brakes must be used moderately during first several hundred miles of operation to ensure proper burnishing of linings.
