Operation
addition, the air gauge(s) will indicate low air pressure in at least
one of the split systems.
The warning buzzer and RED indicator automatically shut
off when the air pressure in both systems is sufficient
(approximately 70 psi [483 kPa]) to operate the vehicle.
If the RED indicator and buzzer do not shut off after start-up,
check the air pressure gauge(s) and see if one or more sections
of the split system has low air pressure.
If the RED indicator, buzzer, and gauge indicate a loss of
pressure while driving, the vehicle will still have some braking
capability. Either one-half of the split system or the spring brake
system braking capability is retained. However, the distance
required to stop the vehicle will be increased.
Air Disc Brakes (0004JBZ, 0004JCC, 0004WEY, 0004WEZ)
The air disc brake system encompasses a floating caliper design
that is activated when air pressure is introduced into the system.
The air disc brake system works by converting air pressure into
braking force. When braking is applied, air will enter the brake
chamber applying pressure to the diaphragm. The pressure
created activates the system causing the brake pads to contact
the rotor. When braking is released, the air pressure in the brake
chamber is released, exhausting the pressure on the diaphragm
causing the brake pads to return to their neutral / non-braked
position.
Using Air Brakes
WARNING
To prevent property damage, personal injury,
and / or death, always check and maintain
brakes in proper condition and adjustment.
Out-of-adjustment brakes could cause reduced
braking ability.
Do not apply and release (pump) the brakes rapidly. This is an
inefficient way of slowing or stopping a vehicle and inefficient use
of air pressure. This also reduces the ability of the ABS system
to function properly.
Using the Air Parking Brake
WARNING
To prevent property damage, personal injury, and
/ or death, before starting the engine, the parking
brake control knob must be in the applied (pulled)
position. Failure to do so could allow the vehicle
to roll.
The purpose of the parking brake is to hold the vehicle in the
parked position. It should NOT be used to brake the vehicle
during normal driving. It may be used to assist in making an
emergency stop in the event of service brake failure.
