What is the key feature of anti-lock brakes?

The key feature of anti-lock brakes (ABS) is that they are designed to prevent the wheels from locking up during hard braking. This allows the driver to maintain steering control while braking. With ABS, the driver simply needs to apply firm pressure to the brake pedal rather than pumping it. This system rapidly modulates brake pressure to each wheel, which helps to achieve maximum stopping power without losing traction.

In contrast, pumping the brakes is required in standard braking systems to prevent the wheels from locking, whereas ABS eliminates this need, allowing for a more straightforward and effective braking response. While anti-lock brakes improve the effectiveness of braking under various conditions, they do not stop the vehicle instantly; rather, they allow for safer braking. Furthermore, they are not limited to icy conditions; they enhance braking performance on dry, wet, and slippery surfaces alike.
