If you try to pump ABS brakes, they will not work. Pumping ABS brakes defeats the computer's efforts to sense a wheel skid. If your vehicle has ABS brakes, when you need to stop in a hurry press the brake hard and hold your foot on the pedal no matter what it feels or sounds like. ABS brakes pulsate, they rattle, and they make noise. Do not release the pedal until you no longer need to brake.
