Chevrolet 1995 S-10 Pickup Owner's Manual page 139

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. With four-wheel
anti-lock: 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
four-wheel anti-lock system can change the brake pressure faster than any
driver could. With rear-wheel anti-lock: If one of the rear wheels is about
to
stop rolling, the computer will work the brakes at the rear wheels. The
computer is programmed to make the most of available tire and road
conditions.
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.
