Question

when stopping your car on a slippery surface, if your car is equipped with anti - lock brakes you should:
push the brake pedal until it vibrates, then release it
pump the brakes
push the brake pedal and hold it even if it begins to vibrate

Explanation:

Anti - lock brake systems (ABS) are designed to prevent wheel lock - up during braking. When using ABS on a slippery surface, the correct procedure is to push the brake pedal and hold it. Pumping the brakes is the old - fashioned method for non - ABS brakes. Releasing the pedal after it vibrates is also incorrect. The vibration of the brake pedal is a normal part of the ABS operation, and the driver should keep the pedal pressed.

Answer:

push the brake pedal and hold it even if it begins to vibrate
