C216Everyone knows that cars and trucks are complex machines with many moving parts that have to all work together to keep your car running and you safe. To help you better understand your vehicle, the ASE-certified technicians at Christian Brothers Automotive Alamo Heights in San Antonio, TX are answering your questions about ABS.

What does ABS stand for, and what does it do?

ABS stands for Anti-lock Braking System. Anti-lock brakes are designed to prevent skidding and help drivers maintain steering control. ABS uses electronic controls and sensors to control braking force during hard braking, while the driver steps on the brakes firmly without pumping the brakes.

Does ABS help me stop faster?

ABS is designed to help drivers maintain control of the vehicle during an emergency braking situation, not make the car stop more quickly. However, there is a slight difference in stopping distance on wet or slippery roads.

What is the difference between rear-wheel ABS and four-wheel ABS?

While all anti-lock braking systems are very similar in the way that they control brake pressure, some prevent only the rear wheels from locking up and others prevent all the wheels. The first, called rear-wheel ABS keeps your vehicle from spinning out of control, but you won’t have control if your front wheels lock up. Four-wheel ABS is designed to keep all four wheels from locking up.

Rear-wheel ABS is usually used for pickup trucks and sport-utility vehicles, whereas four-wheel ABS is used in cars and minivans. If you have a pickup or SUV, check your owner’s manual to see which ABS you have.

Why is my ABS light on?

There are quite a few reasons as to why your ABS light may be on, including:

  • Damaged wheel sensor
  • Broken/missing wheel sensor signals
  • Damaged or dirty tone ring
  • Malfunctioning pump motor
  • Loss of power assist
  • ABS pump keeps running
