What happens when the ABS is activated during braking?

When the Anti-lock Braking System (ABS) is activated during braking, the primary function of the system is to regulate air pressure to the brakes. This regulation helps prevent the wheels from locking up, which can lead to skidding or loss of control.

The ABS operates by using sensors to monitor the rotation of each wheel. If it detects that a wheel is beginning to lock up, it automatically modulates the brake pressure, rapidly applying and releasing the brakes at the affected wheel(s). This allows the driver to maintain steering control, particularly in emergency braking situations.

The selection of regulating air pressure directly correlates with the purpose of ABS, as this is essential for maintaining traction and avoiding uncontrolled skidding.
