Note: One of the most common omissions in maintaining a modern Anti-lock Brake System (ABS) is checking out the speed sensors. These sensors are often located at each wheel hub/rotor on four-wheel disc systems. Alternatively, on rear-drum applications, you'll usually find them mounted on the differential housing. Whatever their location, they supply information regarding wheel speed to the ABS computer. Under breaking, if wheel speeds are not equal, indicating wheel lockup, the computer modulates the anti-lock feature until the speeds are equal again.

Please check compatibility prior to purchasing. If you are not able to locate part numbers, you may call your local dealership (auto parts department), provide your vehicle information and obtain correct part number(s). Feel free to contact us should you have any questions. Read an article if you would like to know more about how ABS system works.
