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, the wheels can potentially stop rotating, which can lead to a loss of traction and control, causing the vehicle to skid. ABS is designed to modulate the braking pressure applied to each wheel, allowing the wheels to continue turning while slowing the vehicle down. This helps maintain steering control and stability during hard stops.

With ABS, the system pulsates the brake pressure multiple times per second, ensuring that the wheels do not completely lock up. This is crucial during emergency situations where quick braking is required, as it significantly reduces the risk of skidding and enhances the driver's ability to steer around obstacles. Overall, ABS contributes to improved vehicle control and safety, particularly in slippery conditions, but its primary role remains focused on preventing wheel lock-up.
