What are Anti-Lock Brakes (ABS)?
Today, most new vehicles are equipped with an anti-lock braking system or offer it as an option, and many car shoppers consider anti-lock brakes a must when they make a vehicle purchase. Designed to give the driver control over the vehicle while coming to a rapid stop, anti-lock brakes employ precisely calculated, rapid pumping action to prevent wheels from locking up during a sudden stop. Anti-lock brake technology marks such a significant breakthrough in the automobile industry that in a 2006 report published by www.cars.com, anti-lock braking technology was rated the #1 automobile innovation in recent years and was credited it for paving the way for roll mitigation and stability control technology.
Let us examine for a moment what happens to a vehicle without ABS as sudden pressure is applied to the brake. The wheel is capable of coming to a stop quicker than the vehicle itself, resulting in a skid as the wheel locks but the vehicle continues to move. When a vehicle skids, there is little traction and the driver has minimal or no control over the direction the vehicle will go.
Anti-lock brakes employ computer controlled speed sensors which detect sudden deceleration and activate right before the point when the wheels would otherwise lock up. By rapidly releasing and reapplying pressure to the brake system in quick intervals, the ABS system allows the tires to decelerate at the same rate as the vehicle, preventing skidding and allowing the driver to steer away from obstacles while braking if necessary. Without ABS, a vehicle in the same situation could lose traction, leaving the driver at the mercy of the out of control vehicle and anything in its path.
Several studies have raised doubt regarding whether the presence of ABS actually prevents accidents, and some experts suggest that drivers being unaware of how to correctly utilize the system contributes to the findings. When you rapidly compress the brake pedal in a vehicle with anti-lock brakes, it is normal to feel a pulsing or vibrating from the pedal, and possibly some noise. In vehicles with ABS, brakes should never be pumped with the foot. In an emergency stopping situation, hold constant pressure on the brake pedal while maintaining a firm grip on the steering wheel to control the direction of the vehicle, allowing the ABS to do the job for which they are designed.
In purchasing a vehicle with ABS, note that all ABS systems are not the same. While some systems include a speed sensor and valve for each of the four wheels, others may have just one valve and sensor for both rear wheels. Consult the owner’s manual for information about the type of ABS system with which a particular vehicle is equipped.
