GMC 1995 Suburban Owner's Manual page 194

Here's how anti-lock works. Let's say the road is wet. You're driving safely.
Suddenly an animal jumps out in front of you.
You slam on the brakes. Here's what happens
with
ABS.
A computer senses that wheels are slowing down. If one of the wheels is
about to stop rolling, the computer will separately work the brakes at each
front wheel and at the rear wheels. The anti-lock system can change the
brake pressure faster than any driver could. The computer is programmed to
make the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on wheel speed and
controls braking pressure accordingly.
Remember: Anti-lock doesn't change the time you need to get your foot up
to the brake pedal. If you get too close to the vehicle in front of you, you
won't have time
to
apply your brakes if that vehicle suddenly slows or
stops. Always leave enough room up ahead to stop, even though you have
anti-lock brakes.
