Brake system

The tandem master cylinder brake system
is a hydraulic system with two separate
sub–systems. If either sub–system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
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 reserved
vacuum for one or two stops—but no
more!
CAUTION
D
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
D
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-
your mal. And your braking distance will
be longer.
ANTI–LOCK BRAKE SYSTEM
The anti–lock brake system is designed
to help prevent lock–up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
