BRAKES

DESCRIPTION AND OPERATION
DESCRIPTION
The mechanical components of the hydraulic braking
system consist of four piston caliper disc brakes at the
front and two piston caliper disc brakes at the rear.
The front brake discs are vented.
A cable controlled parking brake operates a single
drum brake mounted on the rear output shaft of the
transfer gearbox and is completely independent of the
main braking system.
The basic hydraulic system involves 2 separate and
independent primary and secondary circuits which
permits a degree of braking should a fault occur in
one of the circuits. The primary circuit operates the
rear brake calipers and the secondary circuit the front
brake calipers.
Master cylinder
A tandem master cylinder, which is assisted by a
lightweight compact servo, is fed by a divided fluid
reservoir. The rear section supplies fluid for the
primary circuit and the front section the secondary
circuit.
