Brake Maintenance

Adjusting the Service
Brakes
Adjust the service brakes when there is more than
2.5 cm (1 inch) of free travel of the brake pedal, or
when the brakes do not work effectively. Free travel is
the distance 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.
1. To reduce free travel of the brake pedals, tighten
the brakes by loosening the front nut on the
threaded end of the brake cable

2. Tighten the rear nut to move the cable backward
until brake pedals have 1.27 to 1.9 cm (1/2 to
3/4 inch) of free travel, before wheel lock up is
achieved.
3. Tighten the front nuts, ensuring that both cables
actuate the brakes simultaneously.
Adjusting the Parking
Brake
If the parking brake fails to engage, an adjustment to
the brake pawl is required.
1. Loosen the 2 screws securing the parking brake
pawl to the frame
