Braking
Service brakes
Push down on the brake pedal to apply the service brakes.
The service brake system has two separate brake circuits. The
system provides reduced braking capability in the event of a brake
line rupture or other failure in one circuit.
Each of the two circuits function on one front and opposite rear
tandem wheel. Should one circuit fail, braking remains effective on
all tandem wheels through the tandem chains.
In the event of service brake system failure, the warning lamp (C)
will illuminate accompanied by the red central warning lamp (B), a
display panel message (D), and a buzzer.
A supplementary power source automatically supplies hydraulic
power assist in the event of an engine failure or any situation
where hydraulic oil flow is interrupted to the service brake system.
Reduced braking capability is still available when the engine is not
running, or the key is not inserted in the ignition switch. Supple-
mentary power source will engage when the brake pedal is de-
pressed with the key either on or off.
This reserve system provides power assisted braking capability at
a reduced level and automatically resets when hydraulic oil flow is
restored.
IMPORTANT! Do not rest your foot on the brake pedal with
the ignition key in the off position. This may damage the
supplementary brake system.
