Prevent Skidding
The best anti-lock brake for cars and trucks engage when you press the brake pedal. Modern cars feature the mandatory braking system to aid in heavy braking situations. The anti-lock braking system uses a computer to help prevent skidding when braking. When the weather is bad, you can hydroplane over the slick puddles of water and oil mixtures on the surface of the road. After depressing the pedal to stop, if the car starts skidding, the ABS relay activates and essentially pumps the brakes repeatedly for you. While you can manually tap the brakes repeatedly to prevent a skid, you may not think about that in the midst of one. The ABS engages a temporary brake pressure release quickly to keep the car from skidding. If the ABS relay fails, the car does not engage the anti-skid capabilities as designed.

ABS Light
When the ABS light or check engine light pop on, it can signal an issue with the anti-lock brake relay. You can take your vehicle to the service station for someone else to diagnose the problem. However, if you want to diagnose the problem yourself, AutoZone shows in any search for anti-lock brake near me. Our local stores feature knowledgeable associates ready to help you troubleshoot your car issues, find you the right parts and help you save money. The service station may charge you hundreds of dollars to diagnose the issue when the anti-lock brake relay is a rather inexpensive and easy part to replace yourself. A problem with the ABS relay quickly affects the entire braking system because it supplies the power. The ABS light or check engine light come on when the relay fails to signal an issue with the ABS system. Replacing the relay is often the first thing you can do to get the ABS system functioning properly.

Heavy Braking
The lowest prices on anti-lock brake are at AutoZone. The ABS system is specifically designed for use during heavy braking usually when the roadway is wet and slippery. If the system doesn't function properly, the wheels can lock and the vehicle can skid potentially causing loss of control or an accident. The brakes may work normally during regular driving conditions but may fail during heavy braking situations. Over time, the ABS relay breaks down and needs replacement. A safe place to test your ABS system is test driving it in an open parking lot or ill-used street. Slam on the brakes hard and see if the pedal pulsates. If it fails to engage, the car may skid so be prepared. To replace the relay, you need standard automotive tools including Allen wrenches and needle nose pliers. Safely set up your vehicle to work on then disconnect the battery. The relay is housed in the fuse box, locate it and remove it.
