Servicing the Brakes

Inspecting the Brakes
Brakes are a critical safety component of the vehicle. As
with all safety components, they should be closely
inspected at regular intervals to ensure optimum
performance and safety. The following inspections should
be done every 100 hours:
Inspect the brake shoes for wear or damage. If the
lining (brake pad) thickness is less than 1/16 inch
(1.6 mm), the brake shoes should be replaced.
Inspect the backing plate and other components for
signs of excessive wear or deformation. If any
deformation is found, the appropriate components must
be replaced.
Adjusting the Brake Pedal
Adjust the brake if the parking brake does not hold, the
brake pedal travel is excessive, or braking power is not
sufficient when the brake pedal is depressed. Check the
adjustment every 200 hours.
1. Turn the ignition off and remove the key.
2. Check the brake cables at the brake equalizer (located
under the dash) and determine approximately how far
up the brake rod the equalizer needs to travel so that
there is no slack in the cables (Fig. 31).

5. Press the brake pedal down fully to raise the brake
lever.
6. Thread the brake rod in or out of the brake equalizer as
needed to remove the slack from the brake cables
(Fig. 31). Do not overtighten the cables.
7. Install the spring into the hole in the brake rod (Fig. 31).
8. Connect the clevis on the brake rod to the brake lever
using the clevis pin and hairpin cotter removed
previously (Fig. 31).
9. Ensure that there is some free play in the brake pedal
before the brake engages. If not, repeat this procedure
until there is.

Inspecting the Tires

Check the tire condition at least every 100 hours of
operation. Operating accidents, such as hitting curbs, can
damage a tire or rim and also disrupt wheel alignment, so
inspect tire condition after an accident.
Check the wheels to ensure that they are mounted securely.
Torque the front bolts to 135–165 ft-lb (183–224 N m) and
the rear lug nuts to 45–65 ft-lb (61–88 N m).
Adjusting the Front
Suspension
The ride height of each side of the vehicle can be adjusted
separately. The ride height should be 8-3/4 to 9-1/2
(22.2–24.1 cm) with the following parameters:
The tire pressure should be at 12 psi (83 kPa).
The vehicle should be driven back and forth a few times
to relax the A-arms.
Measure the ride height with the wheels facing straight
ahead and a 175–225 lb. (79–102 kg) operator in the
driver's seat.
Note: The driver should drive up to the measurement
area and stay seated in the vehicle while the
measurement is being taken.
Measure the ride height on a flat surface, from the
bottom of the front tongue to the ground.
1. Jack the front end of the vehicle off of the ground; refer
to Jacking the Vehicle, page 23.
2. Remove the travel limiting bolt (Fig. 32).
3. Loosen the centering bolts in the front A-arm (Fig. 32).
4. Remove the ride height adjustment bolt (Fig. 32).
