can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

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.
To Use Anti-Lock:
Don't pump the brakes. Just hold the brake pedal down
and let anti-lock work for you.
When you start your vehicle and begin to drive away,
you may hear a momentary motor or clicking noise..And
you may even notice that your brake pedal moves a little
while this is going on. This is
the
ABS system testing
itself. You may also hear this during a hard stop.
