CONTROLS AND INSTRUMENTS
Note :
For motorcoaches equipped with the
Anti-lock Braking System (ABS), if the wheels
start to lock-up on slippery roads, the output
retarder will automatically deactivate until the
wheels turn freely.

RAKES
The coach is equipped with a dual braking
system. The front brakes operate differently from
the drive and tag axle brakes.
The dual braking system becomes a modulated
emergency system if a pressure drop occurs in
the rear brake system.
Service brakes are applied by depressing the
brake pedal. Braking increases with the amount
of pressure applied to the foot pedal. Refer to
"Other Features" chapter 4 under "Anti-lock
Braking System". When the brake pedal is
depressed, the brake lights turn
ON
automatically.
For safe and effective braking, the air system
pressure should reach at least 95 psi (655 kPa)
in both the primary and secondary circuits.
A warning light and a buzzer will sound when
the air pressure in either the primary or
secondary circuits drops below 70 psi (483 kPa).
If this occurs, stop the coach, determine the
cause of the pressure loss before proceeding.
Warning :
Immediately report any brake
system problem to the maintenance service
personnel.
Warning :
Do not "fan" or "pump" the brake
pedal. This practice does not increase brake
system effectiveness but rather reduces system
air pressure causing reduced braking
effectiveness.
Caution :
"Riding" the brake by resting
one's foot on the brake pedal when not braking
can cause abnormally high brake temperature,
can damage and cause premature wear of brake
components and reduce brake effectiveness.
