Brake system
TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other will still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may
come on.
Do not drive your vehicle with only
a single brake system. Have your
brakes fixed immediately.

BRAKE BOOSTER

The brake booster uses engine vacuum to
engine
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops—but no
more!
CAUTION
!
CAUTION
!
S Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re-
serve.
S Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard—much harder than nor-
mal. And your braking distance will
be longer.
