Spring Brakes
The spring brakes are applied automatically whenever
there is a loss of air pressure in the braking system or
when the parking brake is activated.
Air Gauges
The pressure gauge on the instrument panel tells you how
much air pressure is in the tank, and whether the system
will operate. An audible buzzer and dash indicator light
warns you if air pressure is insufficient for proper brake
operation.
Brake System Warning Light
This light tells you that your brake system needs servicing.
This light comes on briefly when you turn the ignition key
to the "START" position, but it normally goes off when
the engine starts. If the light stays on or comes on while
driving, have the brake system serviced.
Your vehicle is equipped with a dual braking system. If
there is a loss of pressure in either the front or rear brake
system, the other will provide braking capability. If a
malfunction occurs in either brake system allowing an
imbalance in system pressure, the "BRAKE" light will
glow when the brake pedal is depressed.
If the "Brake" light malfunctions and the air brake reser-
voir is completely empty, the service brake will still
function momentarily to stop the vehicle.
Air Pressure Warning Light/Buzzer
The light/buzzer tells you the air brake system air pressure
is low. This light/buzzer will normally come on when you
first start the engine but will go off when the air pressure
in the air tanks reach approximately 60 psi.

CAUTION
If the "BRAKE" light glows,
other than momentarily
with the ignition in the
"START" position, the
braking system should be
serviced immediately.
If the "BRAKE" light fails
to glow momentarily when
you start the engine, have
the electrical system
checked immediately.
CAUTION
If this light/buzzer comes
on any time other than
at vehicle start up, there
is a problem with the
air system and you
should pull over and
have the vehicle service
immediately.

NOTE
The parking brake will
not disengage until
air
pressure has reached 60
psi.
