Brakes operate most effectively when there is maximum friction between the tires and the road surface. When braking, the tire begins to slip on the road surface and the peripheral speed of the wheel becomes less than the speed of the vehicle. Tire slip is zero when the wheel rotates freely and reaches 100% when the wheel locks. Maximum brake efficiency is achieved with a slip coefficient of 15%.
With this value of the slip coefficient, reliable control and the best stability of the car are ensured.
The purpose of the anti-lock braking system is to instantly limit the pressure in the brakes to obtain the optimal value of the wheel slip coefficient. It acts instantly on the brake of each wheel, reacting to changes in the properties of the road surface or the load on the wheel.
