Hand brake (parking brake)
Hand brake is integral with spring
brake actuator on rear axle. Spring
brake chamber piston ram acts
directly on push rod assembly of
brake chamber.
Parking brake adjustment
No separate adjustment is required.
Service brake adjustment holds good
for hand brake also.
Releasing automatically applied
parking brake
If there is air leakage in parking brake
circuit, parking brake gets applied
automatically. Air leakage in any
other circuit (front, rear and exhaust
brake) does not effect parking brake
due to the action of system
protection valve. A mechanical ‘wind
off’ screw (M16 x 1.5) is provided at
the top of spring brake actuator to
release automatically applied parking
brake due to any reason.
To release, rotate wind off screw up
with a spanner against the tension of
spring (inside spring brake chamber)
till brakes are completely released.
Wind off screw has to be turned back
to original position, soon after
mechanical wind off requirement is
over and before vehicle is put on
road again.
