Braking Operation
Please refer to the specific configurations of your vehicle.
Antilock braking system (ABS)
The Antilock Braking System (ABS for
short) is a mechanical-electrical integration sys-
tem designed to prevent the locking of wheel
due to large braking force (especially on smooth
road) to get the most effective brake and brake
operation stability, and further to avoid traffic
accidents and to reduce the damage from acci-
dents.
The system keeps the control of the vehicle traveling direction in emergency
braking, reduces traffic accidents, improves driving safety, and lessens tire wear and
cost of maintenance.
When the tractor ignition switch is at ON position, the ABS will make self-inspec-
tion (the solenoid valves may make “pull-in” sound in turn), and the tractor ABS mal-
function indicator lamp will stay on for about 3s and then go out. If the tractor ABS
malfunction indicator lamp stays on, it indicates that the ABS is faulty. In this case,
please contact the Technical Service Center (Station) authorized by Dongfeng Com-
mercial Vehicle Company immediately for troubleshooting.
Electronically Controlled Brake System (EBS)
Compared to the traditional brake system, the electronically controlled brake sys-
tem (EBS for short), designed with an electronically controlled air brake, can eliminate
the defects, such as slow response of mechanical brake, poor braking comfort, etc. In
case the electronically controlled return circuit of EBS is in failure, the air pressure
control circuit of EBS, as the standby control circuit, can guarantee braking perfor-
mance of the brake system.
EBS is designed with brake management, ABS, ASR and EBS diagnostic func-
tions, and also with optional ESC, etc. as auxiliary function platform.
Electronic Stability Control System (ESC)
The electronic stability control system (ESC for short) is designed as an active
safety system for assisting the driver to control the vehicle. It can strengthen stability
of the vehicle under bad driving conditions and increase the control range of driver, so
that the vehicle can still be under control in case dangerous and unpredictable condi-
tions.
ESC can determine the driver's intension via various sensors, and automatically
interfere with stability of the vehicle before the stability reaches the critical status, that
is, it will control the output torque of the engine, and apply braking force on one or
