How often does the ABS pulse the brake pressure when skidding is detected?

The correct answer indicates that the Anti-lock Braking System (ABS) pulses the brake pressure up to 20 times a second when skidding is detected. This rapid pulsing is a crucial feature of ABS, as it helps to prevent the wheels from locking up during hard braking. When skidding occurs, the system automatically reduces and then increases brake pressure repeatedly, which allows the driver to maintain steering control while braking. This enhances vehicle stability and helps avoid accidents.

The frequency of up to 20 times a second is significant because it allows for quick adjustments to braking, enabling the driver to respond effectively to changing road conditions and avoiding a complete loss of traction. Understanding this function is vital for drivers, as it can lead to safer driving practices in situations where traction is compromised.
