As required by federal law, all modern cars that you see out on the road are equipped with anti-lock braking systems (ABS). However, many drivers are unaware of what ABS is and how it differs from conventional brakes. In this month’s blog, we discuss the life-saving functions of ABS and common problems car owners may come across.

The Function of ABS

In the case of emergencies and slippery traction, ABS restores traction to the wheels and helps you regain steering control. It stops the wheels from locking up and skidding as well as preventing uneven tire wear. When ABS is activated, it will begin to “vibrate and groan”. This may seem concerning at first and many may think their brakes are failing, but the vibration actually comes from the brakes pulsing numerous times per second. Once you feel or hear the ABS vibrating, continue to firmly press and hold the brake as you steer to safety. If your vehicle does not have ABS or the ABS fails, then you should pump the brake pedal to gain control.

How Do They Work?

Your vehicle’s wheel sensors will recognize when the tires begin to lock up and the ABS will immediately be activated to repeatedly apply and release the brakes in order to prevent skidding. The brake fluid pressure in each wheel will be automatically adjusted to maintain ideal brake performance – which is controlled by an electronic control unit within the system. This pumping action is what differs ABS from conventional brakes when it comes to quickly stopping and maintaining control.

In addition, there are actually two different types of ABS: four-wheel and rear-wheel. Most new cars and minivans have four-wheel ABS which helps with steering. While rear-wheel ABS are usually found in certain SUVs, pickup trucks, and vans. This type of ABS is meant to keep the vehicle from spinning out on slick pavements rather than assist in handling and control. Car owners can check what type of ABS they have by referring to their owner’s manual. An ABS icon will also be on your car’s dashboard when you turn it to accessory mode.

Common Problems with ABS

Many drivers dread seeing an unfamiliar dashboard icon appearing. Your vehicle’s ABS icon lighting up may either be indicating that it’s being activated or there may be an issue reducing the braking effectiveness. If there are any problems, it can be due to a variety of factors including:

  • Contaminations in the brake fluid
  • Sensor contamination
  • Improperly inflated tires
  • Worn-down tread on your tires
  • Leaks
