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 your brakes fixed immediately. Brake booster The brake booster uses engine vacuum to power-assist the brakes.

STARTING AND DRIVING
313
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 your 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 reserve vacuum for
one or two stops but no more!
