Brake Maintenance
Adjusting the Service Brakes
Adjust the service brakes when there is more than 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 (Figure 52).

2. Tighten the rear nut to move the cable backward until
brake pedals have 1/2 to 3/4 inch (1.27 to 1.9 cm) 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 (Figure 53).
