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
both rear wheels.
The anti-lock system can change
the
brake pressure
fdster 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.
