At achievement by the car of speed of movement of 6 km/h there is an automatic check of operability of ABS. Thus it is possible to hear a characteristic sound.
When district speed of any wheel becomes less speed of the car and a wheel there is on the verge of blocking a pressure in a drive of the brake mechanism of this wheel decreases. Pressure regulation in a drive is carried out separately on forward wheels, pressure in a drive on both wheels is behind regulated. Thanks to it braking of both back wheels identical, and stability of the car remains so good as far as it in general is possible under these road conditions. This process of regulation can be noticed on pulsing movements of a pedal of a brake and on a specific sound. It should be some kind of prevention for the driver that one or several wheels start to be blocked. In order that ABS operated optimum, it is necessary to hold when braking a pedal of a brake constantly pressed and not to do at all pumping-up movements. |
