What is the main benefit of using anti-lock brakes (ABS)?

The main benefit of using anti-lock brakes (ABS) is that they help maintain steering control during hard braking. When a driver applies the brakes forcefully, especially on slippery surfaces, traditional braking systems can cause the wheels to lock up. This leads to a loss of traction and control, making it difficult for the driver to maneuver the vehicle. ABS prevents wheel lock-up by modulating brake pressure to each wheel, allowing the driver to maintain steering ability and navigate around obstacles while braking hard. This contributes significantly to safety, particularly in emergency situations.

While reducing overall stopping distance is an important aspect of vehicle safety, ABS primarily enhances control rather than just stopping distance. Similarly, preventing the engine from stalling during a stop or automatically adjusting tire pressure are not functions of ABS; these involve different systems in the vehicle designed for distinct purposes. Hence, knowing the core functionality of ABS helps in understanding its critical role in vehicle safety during intense braking scenarios.
