REAR DRUM BRAKE ADJUSTMENT
- Block the front wheels and release the parking brake. Raise and support the rear of the vehicle on jackstands.
- Depress the brake pedal two or three times and release.
- The adjuster is located on the inboard side, underneath the control arm. Turn the adjuster clockwise until the wheel no longer turns.
- Back off the adjuster two (2) clicks and turn the wheel to see if the brake shoes are dragging. If they are dragging, back off the adjuster one more click.
BRAKE PEDAL FREE-PLAY
See Figure 1
Free-play is the distance the pedal travels from the stop (brake light switch) until the pushrod actuates the master cylinder.
To check free-play, first measure the distance (with the carpet removed) from the floor to the brake pedal. Then disconnect the return spring and again measure the distance from the floor to the brake pedal. The difference between the two measurements is the pedal free-play. The specified free-play is 0.04-0.2 in (1.0-5.0mm). Free-play adjustment is made by loosening the locknut on the brake light switch and rotating the switch body until the specified clearance is obtained.
