A load conscious pressure reducing valve eliminates the
possibility of rear wheels from locking and achieves optimum
braking in any load condition of the vehicle.
The valve, is fitted on RH long member connecting it to rear
axle through its link and control spring.
If any, alteration is done in rear suspension, the performance
of this valve will be impaired.

The by-pass valve is provided in the rear brake circuit between
tandem master cylinder and ABS unit. The by-pass valve
bypasses the ABS unit in rear only braking (i.e. front brake
failed) condition. The feedback of front line pressure is
provided to the by-pass valve. in case of front brake failure,
the low front line presure being sensed by the by-pass valve
and the 100% brake line pressure from tandem master
cylinder is applied on to the rear brakes without reduction
in pressure.

ECU :
DICOR engine common rail system consists of ECU, sensors
and actuators. The Electronic control unit (ECU) is a 32 bit
microprocessor which controls the injection parameters as well
as some of the vehicle related outputs. The ECU receives input
from various sensors located on the engine and the vehicle to
decide the injected quantity and injection timing best suited
for the engine to work with maximum efficiency and safety.
ECU is fitted inside the engine compartment.
