The principle of operation of the brake system

Brakes work most effectively with maximum tire friction on the road surface. When braking, the tire begins to slip on the road surface and the circumferential speed of the wheel becomes less than the speed of the vehicle. Tire slip is zero when the wheel is free to rotate and reaches 100% when the wheel is locked. The maximum efficiency of the brakes is achieved with a slip coefficient of 15%.

With this value of the slip coefficient, reliable handling 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 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.
