Anti-lock Brake Systems are widely used in vehicles today to prevent skidding during emergency brake maneuvers. In a car without ABS, if the brakes are applied and a wheel stops spinning while the vehicle is still in motion, the driver will no longer have control over that wheel. That loss of control could lead to skidding and the inability of the driver to steer properly. A car with ABS, however, will be able to control all four wheels even if they’ve stopped moving. This is because each wheel has a speed sensor attached that relays information to a central ABS computer. If a wheel does stop spinning, the ABS computer will pump hydraulic pressure to that wheel, essentially releasing and then reapplying the brakes. The main issue that arises with Anti-Lock Brakes is faulty sensors. If the speed sensors are not working, the ABS computer won’t know when or to which wheel it needs to pump brake fluid pressure. At Lake Norman, we recommend that you have your sensors tested when you’re having any other brake maintenance or repairs performed. If your ABS light comes on, bring your car in as soon as possible.
