Chevrolet 1998 Lumina Owner's Manual page 169

If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist
is used up, it may take longer to stop and the brake
pedal will be harder to push.
Anti-Lock Brakes (Option)
Your vehicle may have anti-lock brakes (ABS). ABS is
an advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock brakes, the brake pedal
will say so.
ANTI -
LOCK
And this warning light on
the instrument panel will
come on briefly when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves or pulses a little. This is normal.
If there's a problem with the anti-lock brake system, the
anti-lock brake system warning light will stay on or
flash. See "Anti-Lock Brake System Warning Light" in
the Index.
