Anti-Lock Braking System - ABS

Under emergency braking conditions or on slippery road surfaces, the Anti-Lock Braking System (ABS) prevents the wheels from locking and maintains your ability to steer the car. Locked wheels can no longer transmit cornering forces, and the car does not respond to steering commands. To prevent this from happening, the ABS control unit monitors the rotational speed of all car wheels by means of wheel speed sensors. If one of them threatens to lock, a solenoid valve in the control unit of the ABS reduces brake pressure for the respective wheel until it runs freely again. The pressure then increases up to the locking limit once more. The car remains stable, and you remain able to easily steer. In modern ABS systems, such as those used in your SEAT model, this process takes place several times a second. The driver perceives the action of the ABS as a slight vibration of the brake pedal. In the ABS control range, your car can be steered easily to avoid obstacles and prevent a collision, even during maximum deceleration.
