BRAKES
The service braking system consists of front ventilated
disc brakes with twin pot caliper and rear drum brakes
with auto adjuster. No adjustment required for front &
rear brakes. These are hydraulically operated and a
dual hydraulic split circuit is provided for front and
rear brakes. Should one circuit fail, the other remains
unaffected and the vehicle can be brought to a halt.
The hydraulic pressure is applied from the tandem
master cylinder to the front and rear wheel cylinders
through suitable bundy tubes/flexible hoses. The
pistons inside the wheel cylinders move out, forcing
the brake shoes/pads on the drums/discs, and applying
the brakes.
To reduce pedal effort, a twin diaphragm vacuum
booster is fitted between brake pedal and tandem
master cylinder. Should the servo unit fail, the push
rod still acts mechanically to provide non-assisted
braking. The vaccum in the system is generated by
vaccum pump in case of diesel vehicle. There is no
vaccum pump for petrol vehicle.
The parking brake is a mechanical lever type, console
mounted cable operated acting on rear wheels.
Anti-lock Braking System (ABS) with Electronic Brake
Force Distribution (If fitted) ensures great stability and
steerability while braking and also avoids wheel
locking, skidding of wheels during panic braking.
Electronic Brake Force Distribution ensures proper
brake pressure distribution on all wheels.
Load conscious pressure reducing valve (LCRV) is
provided in rear brake circuit to avoid locking of rear
wheels and skidding of the vehicle for non-ABS
versions.
