Operation
Instrument Panel Gauge Cluster indicators identify brake system
fault conditions. Certain faults may also result in cluster alarms.
The following lists some of the common faults (See
Warning
Indicators in Instrumentation section):
Split-System Feature
WARNING
To prevent personal injury and / or death,
or damage to property, if part of the brake
system fails, reduce speed and use caution as
stopping distance may increase under the failed
condition or if only one section of the brake
system is operating. Have brake system repaired
immediately.
Loss of braking capability could
cause an accident.
WARNING
To prevent personal injury and / or death, or
damage to property, under no circumstances
should
the parking brake chamber be
disassembled. Disassembly will release a
powerful spring that could result in property
damage, personal injury or death.
The system is divided into two separate channels: the primary
channel (controls front axle) and the secondary channel (controls
rear axle). The brake master cylinder is connected to brake lines
that are routed to the front and rear brake channels.
With the split brake system, the operator is has limited brake
control should one of the two channels fails. If one of the motor
/ pump related systems fail, the driver may not detect any
difference in the feel of the pedal, but with a failure in the master
cylinder circuit, the driver may experience a longer pedal stroke
to attain desired stopping. If a brake system failure occurs,
one of the Instrument Panel Gauge Cluster warning indicators
should illuminate.
Manual Foot Operated Parking Brake System with
Hydraulic Brakes
WARNING
To prevent personal injury and / or death, or
damage to property, when parking your vehicle,
always use the parking brake. When parking on a
grade, install wheel chocks and turn front wheels
to keep the vehicle from rolling into the traveled
portion of the roadway. Failure to follow these
procedures could cause an unattended vehicle
to move, resulting in property damage, personal
injury or death.
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.
The manual parking brake is controlled by the parking brake
pedal. Always observe the Instrument Panel Gauge Cluster
PARKING BRAKE indicator to determine if the parking brake is
applied or released.
