Vehicle Inspection Guide
Inspect for excessive free play in the steering
linkages. The steering wheel should have less
than 2 inches (5 centimeters) of free play at its
rim.
Pump the brake pedal several times with the
ignition in the off or run position. You can
momentarily hear the motor and pumps
replenishing the accumulators.
Verify the parking brake holds the vehicle by
gently trying to pull forward with the parking
brake applied.
Verify operation using the following procedure.
Chock the wheels, if necessary. Push in the
parking brake and, on tractors, push in the
tractor parking brake knob:
1. Verify the air compressor or governor cutout
pressure is approximately 120 psi (827 kPa).
2. Turn off the engine, and then turn the key
back to the on position (without starting the
engine).
3. Without the brake pedal applied, note the air
pressure drop for one minute. It should be less
than 2 psi (14 kPa) for single vehicles and 3 psi
(21 kPa) for combination vehicles.
4. Press and hold the brake pedal with 90 psi
(621 kPa) or more. Make sure there is no more
than a 3–psi (21 kPa) per minute leak for single
vehicles and a 4–psi (28 kPa) per minute leak for
combination vehicles.
5. Pump the brake pedal to deplete the system of
air pressure. The warning light and tone should
turn on at 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.
Verify that the fluid level is in the proper
operating range. See Transmission fluid check
in the Maintenance chapter.
