10.2. The general information

The scheme of brake system

1 – switch ASR,
2 – the switch of a stoplight,
3 – the gauge of speed  of rotation of a back   left wheel,
4 – the gauge of speed of rotation of a back  right wheel,
5 – the gauge of speed of rotation of a right forward wheel,
6 – the gauge of speed of rotation of a left forward wheel,
7 – the block of management ABS/EBV/EDS/ASR/ESP,
8 – control lamp ABS/EDS,
9 – control lamp ASR/ESP,
10 – a control lamp of level of a brake liquid,
11 – the main brake cylinder, the vacuum amplifier of brakes and a pedal of a brake,
12 – the hydraulic block

The forward brake of firm Teves established on cars with capacity more 81 kw (110 h.p.)

1 – a brake hose,
2 – a protective cap,
3 – a directing finger, 25 Nanometers,
4 – the brake pipeline, 15 Nanometers,
5 – a support,
6 – a bolt, 120 Nanometers,
7 – a support,
8 – brake колодки,
9 – a spring,
10 – a brake disk,
11 – an arm,
12 – a bolt, 10 Nanometers

The prevention

At replacement brake колодок do not unscrew a brake hose 1.

Before ввинчиванием a bolt 6 clear the ridge basis of a head of a bolt.

The spring 9 is established in two apertures of a support.

In need of replacement replace both lobbies of a brake disk 10. Before removal of a brake disk it is necessary to remove a support.

According to the destination and to carried out functions the brake system is divided on working, spare, lay and emergency. The working brake system provides regulation of speed of the car and its stop with necessary efficiency. The spare system serves for a stop of the car with necessary efficiency at failure of working brake system. The lay system serves for car deduction are motionlessly rather expensive. To it basically use for deduction of the standing car, but it can be applied and as emergency at failure of working brake system.

On the car the working brake system with a hydraulic drive and diagonal division of contours is applied that considerably raises safety of driving of the car. At refusal of one of contours as spare brake system the second contour providing a stop of the car with sufficient efficiency is used.

The brake system consists of the main brake cylinder, the vacuum amplifier of brakes and disk brakes on forward and back wheels.

The tank with a brake liquid is in a motor compartment over the main brake cylinder and supplies brake system and coupling brake a liquid. The vacuum amplifier of brakes reduces effort to a brake pedal, facilitating thereby driving.

The brake mechanism of a forward wheel disk with a mobile support. It is well entered in a wheel, has a small amount of details, including consolidations and small weight. As теплоотдача occurs through one cylinder, the brake liquid heats up less.

The manual brake influences back wheels through тросовый a drive.

The prevention

At work brake колодок the brake dust which contains asbestos, unhealthy is formed, therefore at clearing brake колодок do not use compressed air and do not inhale a dust.

At movement on damp road it is recommended to press from time to time a brake pedal to remove from brake disks harmful inclusions. At the expense of centrifugal force water at movement is dumped from brake disks, however on them there is a thin film from fats, силиконов, the rests of rubber, greasing and a dirt which reduce efficiency of braking. At a stop of the car after movement in the rain in the end of movement it is recommended to dry brakes pressing a brake pedal.

After installation new brake колодок they should be earned extra. On the first 200 km of run it is not recommended to make the maximum braking needlessly.

Корродированные brake disks cause vibrating effect which does not disappear at long braking at braking. In this case brake disks are subject to replacement.

The brake liquid used in hydraulic system of brakes is poisonous, therefore at its hit on a skin it is necessary to wash out immediately this place a plentiful quantity of water. If the liquid on imprudence has got to eyes or in an organism, it is necessary to address immediately to the doctor. Some liquids have property easily to ignite and can light up even from contact to hot knots of the car. Besides, the brake liquid dissolves a paint and plastic, therefore at liquid hit on a paint and varnish covering of the car, wash out its plentiful quantity of water. Also this liquid гигроскопична, that is absorbs a moisture from air and consequently a liquid, stored long time in open ware is not recommended to be used.

The brake liquid should not contact with mineral oils. Even the small amount of mineral oil puts out of action a brake liquid and brake system.
