What are antilock brakes system? Antilock brakes are designed to help drivers avoid crashes. Without anti-locks, hard braking can cause wheels to lock, sending a vehicle into a skid. Wheel lockup can result in longer stopping distances, loss of steering control and, when road friction is uneven, loss of stability if the vehicle begins to spin. The main advantage of anti-locks is that they can reduce these problems on wet and slippery roads. Anti-locks work with a vehicles normal service brakes to decrease stopping distance and increase the control and stability of the vehicle during hard braking. The principle behind anti-locks is that a skidding wheel provides less stopping force and control than a wheel that is rotating. Anti-locks prevent wheels from skidding by monitoring the speed of each wheel and automatically pulsing the brake pressure on any wheels where skidding is detected. Anti-locks dont make much difference in stopping distances on dry roads, although they can enhance vehicle stability and allow drivers to maintain steering control during emergency stops when conventional brakes might allow wheel lockup and skidding. How do antilock brakes system? Since most cars on the road today have some form of Antilock Brakes (ABS) I think we should take a look at how they work and clear up some mis-information about them. As always, what I describe here is how most systems work in general. Since different manufactures have their own versions of ABS their values, specifications and part names will differ. If you are having a problem with the ABS on your vehicle you should always refer to the specific service and repair manuals for your vehicle. The ABS is a four-wheel system that prevents wheel lock-up by automatically modulating the brake pressure during an emergency stop. By preventing the wheels from locking, it enables the driver to maintain steering control and to stop in the shortest possible distance under most conditions. During normal braking, the ABS
