BRAKE EQUIPMENT (MODELS WITH FULL AIR BRAKE) BR01–2
SERVICE BRAKE ASSEMBLY
DESCRIPTION
EN0680201C100001
Type of service brake Full air, S-cam brake (Q-plus) with automatic adjuster.
Air charging system Air charging is from piston type air compressor and air flow is directed and
controlled by a pressure regulator, the necessary valves, and lines as
required.
Pressure sensor and air pressure warning switch are used for indicating
the pressure level in the system.
Service brake control system Two independent lines for front and rear wheels with air flow controlled by
a brake valve, and each line comprises of a group of valves and brake
chambers (one/wheel).
Two stop light switches (one/line) are used to operate the stop lights.
Spring brake control system Single line for rear spring brake chambers.
The line comprises a control valve which controls air flow, the other neces-
sary valve and spring brake chambers.
A parking brake switch is used to turn OFF the warning buzzer and to turn
ON the parking brake warning light.
ABS (Anti-Lock Braking System) The ABS system comprises sensor rings mounted on the wheels, the ABS
ECU which receives signals from wheel sensors that monitor the rotational
speed of the wheels and sends out signals to maintain the appropriate
braking force, the ABS control valves which increase or decrease the brak-
ing force based on the control signals.
