Brake Maintenance
Adjusting the Parking Brakes
Adjust the brakes when there is more than 25 cm (1 inch)
of free travel
(Figure
71) of the brake pedal, or when more
holding force is required. Free travel is the distance that the
brake pedal moves before you feel braking resistance.

1. Free travel
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

brake pedals have 6.3 to 12.7 mm (1/4 to 1/2 inch) of
free travel
(Figure

3. Tighten the front nuts, ensuring that both cables
actuate the brakes simultaneously.
Note: Ensure that the cable conduit does not rotate
while you are tightening the nuts.
