9.6.1. Action principle

The brake system operates most effectively at the maximum coupling of the tire with a paving. When braking the tire starts to slide on a road surface. Thus, speed of rotation of a wheel becomes less, than speed of movement of the car. Sliding is minimum (0 %) when the wheel freely slides, and is maximum (100 %) when it is blocked. Maximum efficiency of action of brakes is reached when sliding about 15 %. At this value sufficient controllability and stability of the car also is provided. ABS provides immediate restriction of brake pressure in brake mechanisms of each wheel for receiving factor of sliding, near optimal, at change of a condition of a paving or loading.
