Stopping safely is one of the most important functions a motor vehicle has to perform. Failure of the brake system will almost invariably result in property damage, personal injury, or even death. Consequently, a great deal of consideration has been given to improving the brake system in trucks and passenger cars over the last nine decades. One of the latest improvements is an antilock brake system which, as the name suggests, prevents a vehicle's brakes from locking up and skidding during hard stops on wet or icy roads. When activated correctly, Anti-Lock Brake Systems (ABS) can provide drivers with the ability to stop a vehicle in shorter distances and allow for more vehicle control under heavy braking than conventional brake systems. This is especially true under wet or icy road. Anti-lock brakes are designed to prevent skidding and help drivers maintain steering control during an emergency stopping situation. In cars equipped with conventional brakes, the driver pumps the brakes, whereas in cars equipped with four-wheel ABS, the driver keeps a firm foot on the brake, allowing the system to rapidly and automatically pump the brakes. Because the wheels don't lock, drivers have the ability to steer around hazards if they are unable to stop in time. Thus, ABS improves vehicle stability, steerability and stopping capability. The most important outcome of the ABS is

Stopping a car in a hurry on a slippery road can be very challenging. Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS

An anti-lock braking system (ABS) (translated from German, Antiblockiersystem) is a system on motor vehicles which prevents the wheels from locking while braking. The purpose of this is to allow the driver to maintain steering control under heavy braking and, in some situations, to shorten braking distances (by allowing the driver to hit the brake fully without the fear of skidding or loss of control).

The idea behind anti-lock brakes is simple. Anti-lock brakes are designed to prevent skidding and help drivers maintain steering control during an emergency braking situation.

ABS eliminates the need to pump the brakes because ABS pumps automatically at a rate of up to 18 times per second whenever a sensor detects the start of wheel lock. ABS works with regular braking system by automatically pumping them. In vehicles not equipped with ABS, the driver has to manually pump the brakes to prevent wheel lockup.

In vehicles equipped with ABS, driver’s foot should remain firmly planted on the brake pedal, while ABS pumps the brakes for you so that one can concentrate on steering. More specifically, ABS automatically changes the brake fluid pressure at each wheel to maintain optimum brake performance—just short of locking up the wheels. There is an electronic control unit that regulates the brake fluid pressure in response to changing road...
