DANGER
Do not adjust the steering wheel while driving.
Loss of control could result. Park the vehicle
safely and apply parking brakes before
adjusting the steering wheel.
BRAKE PEDAL
The coach is equipped with a dual braking
system. The front brakes operate from a different
air source than the drive and tag axle brakes.
The dual braking system becomes a modulated
emergency system if a pressure drop occurs in
the primary brake system (rear brakes).
Service brakes are applied by depressing the
brake pedal. Braking increases with the amount
of pressure applied to the foot pedal. Refer to
"ANTILOCK BRAKING SYSTEM (ABS)" on
page 13
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 in both the
primary and secondary circuits.
A warning light and an audible alert will sound
when the air pressure in either the primary or
secondary circuit drops below 85 psi. If this
occurs, stop the coach; determine the cause of
the pressure loss before proceeding. The brake
pedal can be used in conjunction with the
transmission retarder. Refer to
Retarder Using the Control Stalk" on page 11
this section.
Immediately report any brake system problem
to your company or directly to the nearest
Prevost or Prevost-approved service center.
Do not "fan" or "pump" the brake pedal. This
practice does not increase brake system
effectiveness but rather reduces system air
pressure thereby causing reduced braking
effectiveness.
"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.
ACCELERATOR PEDAL
Controls engine RPM as needed.
