Fig. Fig. 1: A tool inserted through the access slot in the backing plate may be used to adjust the drum brakes

The drum brakes are self adjusting and do not normally require attention. However, if the brakes are disassembled, they must be adjusted upon assembly; or, if necessary, the brakes may be manually adjusted during the course of normal service.

  1. Remove the rubber plug from the access slot on the backing plate.

It may be easier to perform Step 1 with the drum removed; however, be sure that the drum is installed properly before beginning adjustment.

  1. Rotate the starwheel with a prytool or an adjoining tool until the wheel will not rotate.
  3. Mark the starwheel and back it off one complete revolution.

In order to back off the starwheel it may be necessary to use a piece of1/8in. (3mm) welding rod to hold the adjusting lever off the adjusting screw.

  1. Install the rubber plug in the access slot.
  3. Make 10-15 hard applications of the brakes while backing the car up and then road test the car.


The front disc brakes require no adjustment as hydraulic pressure maintains the proper brake pad-to-disc contact at all times.

Because of this, the brake fluid level should be checked regularly (see General Information and Maintenance ).
