How does ABS function during braking?

The function of Anti-lock Braking System (ABS) during braking is primarily to prevent wheel lock-up, which helps maintain steering control and stability during a hard braking event. When a driver applies the brakes forcefully, ABS monitors the rotation of each wheel. If it detects that any wheel is about to lock up, it automatically modulates the brake pressure—essentially pulsing the brakes on and off quickly. This rapid pulsation prevents the wheels from locking and allows the driver to maintain steering control, making it possible to maneuver around obstacles even while braking.

This system is particularly valuable in emergency situations, as it enhances both safety and vehicle control, enabling drivers to avoid potential collisions while stopping. Therefore, the statement regarding the pulsating of brake plates to maintain steering accurately reflects how ABS operates.

In contrast, locking the wheels completely would lead to a loss of steering control, thus negating the benefits of ABS. The system does not limit its effectiveness to only wet roads; it operates in a variety of conditions, and it does not eliminate the necessity of foot braking, as the driver still needs to apply the brakes when needed.
