What is the primary function of an anti-lock braking system (ABS)?

The primary function of an anti-lock braking system (ABS) is to prevent wheel lock-up during hard braking. When a driver applies the brakes forcefully, especially on slippery surfaces, the wheels can lock, causing a loss of traction and preventing the driver from steering the vehicle effectively. ABS works by automatically modulating brake pressure to ensure that the wheels continue to rotate, allowing the driver to maintain steering control while decelerating.

This system helps to improve vehicle control during emergency stops and enhances safety by reducing the likelihood of skidding. The ability to steer while braking is critical in avoiding obstacles and maintaining overall control of the vehicle. The technology behind ABS includes sensors that monitor wheel speed and control modules that adjust brake pressure accordingly, providing a significant advantage over traditional braking systems during challenging driving conditions.
