ABS prevents wheel lockup and loss of steering control during hard braking. It works by continuously monitoring wheel speed and adjusting brake pressure as needed to allow rotation. This helps maintain vehicle control and reduces braking distances compared to regular brakes without ABS. While effective for safety, ABS systems are more expensive to install and maintain than regular brakes alone.
