The general information and security measures

The general information

Forward and back wheels of all cars considered in the present Management are equipped by disk brake mechanisms.

The brake system consists of the main brake cylinder, the vacuum amplifier and disk brake mechanisms of forward and back wheels and is divided under the diagonal scheme into two independent hydraulic contours. At refusal of any of contours (for example, as a result of hermetic sealing infringement) the second continues to function in a normal mode, providing adequate braking of a vehicle. In addition the valve-regulator of pressure providing dynamic updating of effort of braking of back wheels according to change of loading on a back axis of the car is built in contours of both back brake mechanisms. Pressure of a liquid in both contours is created having тандемную a design by the main brake cylinder (ГТЦ). Activation ГТЦ occurs at squeezing of a pedal of a working brake.

The short description of principles of functioning of system of antiblocking of brakes (ABS) is resulted in the Part Receptions of operation and auxiliary systems.

The tank with a brake liquid is fixed on the main brake cylinder (ГТЦ). The amplifier of brakes accumulates a part of the vacuum created in the inlet pipeline of the engine.

The lay brake with manual (on the European models) or foot (on the American models) a drive influences through cables on special башмачные the assemblages which are a part of disk brake mechanisms of back wheels.

Security measures

The brake liquid is among highly toxic and chemically aggressive connections and at contact with кузовными panels destroys a paint and varnish covering!

The brake dust developed in the course of wear process brake колодок, can contain unhealthy the person asbestos, - at all do not inhale it at clearing of brake mechanisms!

Work with brake system demands special cleanliness and exact observance of instructions. In the absence of necessary experience it is expedient to address on HUNDRED.

At movement on wet roads it is necessary to press periodically a pedal of a brake for removal of a moisture from brake disks; In the course of rotation of a wheel the moisture under the influence of centrifugal force is dumped from brake disks, but there is a silicone film, products истирания rubbers, greasing and the other pollution reducing efficiency of braking!

The disk brake mechanisms damaged by corrosion at braking create the effect of jolting which is not disappearing in due course. In that case it is necessary to replace disks.

Dirt burning to a surface brake колодок lead to formation of furrows on a surface of brake disks that leads to decrease in efficiency of braking.
