air (do not use water). Repeat the step from the front
of the radiator and again from the fan side.
4. After the radiator is thoroughly cleaned, clean out any
debris that may have collected in the channel at the
radiator base and around the frame. Also, clean out the
engine compartment and the brake linkage to ensure
optimum performance.
5. Close the clean-out cover and secure the flange nut.
6. Close the hood.
Brake Maintenance
Adjusting the Service 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 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
the brake pedals have 1.27 to 1.9 cm (1/2 to 3/4 inch)
of free travel, before wheel lockup is achieved.
3. Tighten the front nuts, ensuring that both cables
actuate the brakes simultaneously.
