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

The primary function of anti-lock braking systems (ABS) is to prevent wheel lock-up during hard braking. When a driver applies the brakes forcefully, especially on slippery surfaces, there is a risk that the wheels can lock up. This means that the wheels stop rotating, which can lead to a loss of steering control and increased stopping distances. ABS works by rapidly modulating brake pressure to each wheel, ensuring they keep rotating and maintain traction with the road. This allows the driver to steer while braking, improving overall vehicle control and safety during emergency stops.

By allowing the wheels to continue turning, ABS enhances the vehicle's ability to stop effectively while also enabling the driver to maintain steering capability. This technology is particularly important in avoiding skidding and promoting safer vehicle handling.
