DESCRIPTION
The braking system comprises a Bendix 'Master Vac' servo unit and tandem master
cylinder operating single piston sliding calipers on each wheel with ventilated
front and solid rear discs. The seperate front/rear hydraulic circuits share a brake
fluid reservoir which incorporates a 'Nivocode' low fluid level warning switch.
This
circuit, which operates a fascia tell-tale lamp, may be checked by
depressing the test button on the reservoir cap.
The handbrake lever connects via individual cables to each rear brake caliper,
and
mechanically operates their hydraulic pistons via a self adjusting mechanism.
