DESCRIPTION AND OPERATION
WARNING: Longer pedal travel is required,
but power assisted braking is available at
reduced efficiency.
3. If brake failure occurs due to a fractured brake
pipe between a servo unit and a wheel, there
may be no pressure in master cylinder. The fluid
warning light will illuminate when level in master
cylinder is low enough to actuate fluid level
switch. Master cylinder and power valve will
operate as for master cylinder failure, BUT, fluid
from power circuit will push all moving parts in
servo cylinder associated with failure to limit of
travel. No pressurised fluid passes to those
brake pistons served by servo cylinder, but all
other pistons in front and rear calipers will be
supplied with direct pressure from power valve.
Pistons served by other servo cylinder retain
braking as fluid from master cylinder is retained
in servo cylinder not associated with the
leakage.
WARNING: Brake pedal travel will be
greater and extra pedal effort will be
required, accompanied by the vehicle
pulling to one side.
