1.6.9. The protivoblokirovochnoe device brake systems

ABS prevents blocking of wheels at braking.
The protivoblokirovochnoe device of brake system (ABS) appreciably promotes increase of active safety of the car. Decided advantage of brake system with ABS in comparison with the usual consists that wheels are not blocked even at emergency тормо жении on slippery road. Thanks to it in the maximum degree controllability and stability of the car remains.

Principle of action ABS
At achievement of speed of the car about 6 km/h there is an automatic process of the control. At this time it it is possible to hear noise of work of the pump.
At propensity of a wheel to blocking pressure in a brake drive of the given wheel decreases. The given process of regulation is appreciable by a pulsation of a brake pedal and accompanied by characteristic noise displays. Thereby to the driver the warning signal about work of one or several wheels in a mode close to юзу is specially given. For maintenance in this mode of optimum effect of regulation by means of ABS keep a pedal of a brake pressed and do not brake at all in some качков.

The amplifier of emergency braking
The amplifier of emergency braking promotes increase in brake force.
The amplifier of emergency braking helps increase in brake force and thus promotes reduction of a brake way. By very fast pressing of a pedal of a brake the amplifier of emergency braking automatically leads up brake force to a maximum, up to intervention противоблокировочного devices of brake system (ABS). Keep a pedal of a brake pressed before reception of desirable effect of braking. Right after release pedals the amplifier of emergency braking is automatically disconnected.
In default противоблокировочного devices of brake system (ABS) the amplifier of emergency braking does not work.
