Adjusting the Brakes
Adjust the service brakes when there is more than 25
mm (1 inch) of free travel of the brake pedal, or when
the brakes do not work effectively. Free travel is the
distance that the brake pedal moves before you feel
braking resistance.
Note:
Use the wheel-motor backlash to rock the
drums back and forth to ensure that the drums are
free prior to and after adjustment.

To reduce free travel of the brake pedals, tighten
the brakes by loosening the front nut on the
threaded end of the brake cable
