Operation
Air Parking Brake Control Knob
Air Brake Gauge
The air operated parking brake has an air gauge and warning
buzzer. When pressure in the parking brake air reservoir has
been reduced to about 57 psi (393 kPa), the buzzer sounds.
A loss of pressure in the control circuit prevents normal operation
of the parking brake.
CAUTION
To prevent property / vehicle damage, if air
system pressure falls below 70 psi (483 kPa),
pull off the roadway, apply the parking brake and
correct the low pressure condition.
If air pressure is reduced to approximately 40 psi (276 kPa) in
both the primary and secondary systems, the parking brakes will
automatically apply.
Parking Brake Indicator Light
The parking brake indicator is illuminated when the parking
brake is applied. During engine cranking period the parking
brake indicator should illuminate. This indicator goes out after
the engine is started if the parking brake is not applied. If the
parking brake is applied, this indicator remains on after engine
has started. If the indicator does not illuminate during cranking
period, the light bulb may be defective.
