What is an anti-lock brake system?
Anti-lock Brakes A braking system that keeps the wheels from locking up during aggressive stopping. Though anti-lock brakes will often shorten stopping distances, their main advantage over non anti-lock systems is their ability to provide the driver will full steering control during full-force stops. A car with locked wheels will not steer! Helps maintain control in emergency stops. Particularly useful on slick pavement. While the driver applies steady pressure to the brake pedal, the system automatically “pumps” the brakes many times per second to prevent wheel lock-up. Often shortened to ABS. If you hold the brake pedal down, your wheels will lock up -- the brakes won't allow them to turn. On a slippery surface, this can cause the car to slide, just as a toboggan will on snow. On cars without ABS, the proper technique is to pump the brakes, which allows the tires to grip the surface while stopping. Anti-lock brakes electronically pump the brakes, and do so much faster than a driver could. Your car will not necessarily stop sooner (in some cases, such as on gravel roads, it may take slightly longer to stop), but you will be able to better control the car's movement, allowing you to possibly avoid a collision. The brake pedal will vibrate, which can cause some people to let off the pedal. If your car has ABS, try a panic stop in a safe place so you'll know what to expect. Anti-lock brakes don't do this every time you put your foot on the pedal, only when the system senses that the wheels are slipping.
It controls the amount of brake pressure to each wheel, if one starts to lock up and skid it releases the pressure to that wheel and keeps the car in a Straight line. hope this helps you.
