General information and security measures General information Lobbies and back wheels of all cars considered in the real Management are equipped with disk brake mechanisms. The brake system consists of the main brake cylinder, the vacuum amplifier and disk brake mechanisms of lobbies and back wheels and is divided according to the diagonal scheme into two independent hydraulic contours. At refusal of any of contours (for example, as a result of sealing violation) the second continues to function in a normal mode, providing adequate braking of a vehicle. In addition the valve regulator of pressure providing dynamic correction of effort of braking of back wheels according to change of load of a back axis of the car is built in contours of both back brake mechanisms. Pressure of liquid in both contours is created by the main brake cylinder (GTTs) having a tandemny design. Activation of GTTs occurs when squeezing a pedal of a working brake. The short description of principles of functioning of system of anti-blocking of brakes (ABS) is provided in the Part Receptions of operation and auxiliary systems. The tank with brake liquid is fixed on the main brake cylinder (GTTs). The amplifier of brakes accumulates a part of the vacuum created in the inlet pipeline of the engine. The parking brake with manual (on the European models) or foot (on the American models) a drive influences through cables the special bashmachny assemblies which are a part of disk brake mechanisms of back wheels. Security measures Brake liquid is among highly toxic and chemically aggressive connections and at contact to body panels destroys a paint and varnish covering! The brake dust developed in the course of wear process of brake shoes, can contain unhealthy the person asbestos, - at all do not inhale it when cleaning brake mechanisms! Work with brake system demands special purity and exact observance of instructions. In the absence of necessary experience it is expedient to address on HUNDRED.
The disk brake mechanisms damaged by corrosion when braking create the effect of jolting which is not disappearing over time. In that case it is necessary to replace disks. Dirt burning to a surface of brake shoes lead to formation of furrows on a surface of brake disks that leads to decrease in efficiency of braking. |
