Antiblocking system of brakes (ABS)

System ABS raises active safety of the car, preventing blocking of wheels at braking. After all blocking of wheels is exclusively dangerous, as forward wheels become uncontrollable, and going юзом back wheels can lead to drift of the car and emission on other party of movement.

System ABS allows in any concrete conditions (at movement on a straight line, on turn, on the asphalted, ice-covered or wet road, etc.) to reduce a brake way to a minimum.

Basically at each braking ABS should solve two problems, providing:
- траекторную stability on the roads different in type of a covering (asphalted, concrete) and being in a different condition (ice-covered, covered with a dirt, snow or on wet roads)
- Reliable controllability and manoeuvrability of the car under the named conditions

The given requirements require essential comments.

ABS does not cancel action of laws of physics. The system cannot prevent a consequence of the braking executed at an insufficient distance to ahead going car, passage of turns with is inadmissible in the high speed or in the presence of danger of hydroplaning. These consequences still remain on conscience of the driver. Presence ABS, safety providing the raised potential, should not provoke you to unduly risky driving.

Features of driving with ABS

After engine start-up alarm lamp ABS on an instrument guard dies away.

The system automatically joins only on reaching speed about 8 km/h. At its falling below 3 km/h АBS it is disconnected, so theoretically at the latest stage of braking of a wheel can be blocked, however in practice it is basic value any more has no.

ABS realises regulation process for fractions of a second. The pedal pulsation under a foot means that braking occurs under control ABS, otherwise, that the driver goes in a boundary mode. Besides, the crackling caused by process of work ABS, reminds the driver of necessity of reduction of speed for conformity with the actual traffic conditions which have changed because of reduction (for example, in connection with ice) friction factor (or couplings) between tyres and road.

On roads with a loose coating (for example, rubble or snow) over the basis with good coupling properties the brake way can appear more long, than at blocking of wheels. Told concerns and movement with chains противоскольжения. Much more important, however, a prize in траекторной stability and controllability of the car.

To keep working capacity ABS in full, do not make to it change. Works on system should be carried out only by forces of representatives on that experts.

Movement on diverse tyres, for example, after installation of a spare wheel (in a combination to three other wheels on which tyres with winter drawing of a protector are mounted) can limit functionality ABS. Therefore the removed wheel needs to be established as soon as possible back.

Malfunction signal is inclusion of alarm lamp ABS on an instrument guard (address to Section Controls and devices). In this case the brake system continues to work as usual order, as well as on cars without ABS. However as soon as possible address on СТОА BMW for check of brake system. Otherwise in it there can be the malfunctions which are difficultly giving in to detection.

The steering hydraulic booster

At a heavy course of a steering it is necessary to check up oil level according to recommendations in the Head Check of levels of liquids.

If difficulties arise at attempt of fast turn of a steering wheel for check it is necessary to address necessarily on СТОА BMW.

At hydraulic booster refusal the effort necessary for turn of a steering wheel increases.
