Brakes, Bleeding the brake system
Brake system
The dual circuit service brake system
operated through the tandem master
cylinder is designed such that one
circuit will continue to provide braking
action if the other circuit fails. This
vehicle is fitted with disc brakes at front
and drum brakes at rear.

Stopping the vehicle after loss of the
brake fluid in one circuit will require
more pedal presssure and pedal travel
than normal. Also stopping distance
will be longer.
Service brakes are vacuum assisted.
In case of failure of vacuum, the
vehicle can still be stopped, however
with a higher effort.

Bleeding the brake system
If the brake pedal becomes spongy,
this may be due to air in the hydraulic
brake system.
Whenever any repair/overhaul or
disconnecting of any brake pipe is
done, or level of brake fluid has
fallen so low that air has been
drawn into master cylinder, it is
necessary to bleed the system to
remove the trapped air.
