2.5.4.5. Replacement of a brake liquid
THE GENERAL DATA

Only at cars without regulation system проскальзывания driving wheels concerning a basic surface (ASR).

The necessary special tool:

 – A round key for отворачивания bolts of the exhaust device;
 – A transparent plastic hose.

Necessary быстроизнашивающиеся details:

 – About 0,5 l of a brake liquid of specification DOT 4.

The brake liquid through a time of brake hoses, and also through a ventilating aperture of a tank absorbs a moisture from air. Because of it eventually operation the temperature of boiling of a brake liquid decreases. At strong нагруженности brakes it can lead to formation of vials of steam in pipelines of a brake drive because of what functioning of system of braking is strongly broken.

Irrespective of run size a brake liquid replace, whenever possible, in the spring, every two year. At numerous trips to mountain areas a brake liquid replace through more short time intervals.

At the reference with a brake liquid observe precaution rules.

Note a strip of felt level of a brake liquid in a tank. After replacement of a brake liquid again restore its initial level. Thanks to it the modulation of a tank of a hydraulic brake drive is prevented at replacement of frictional overlays brake колодок.
PERFORMANCE ORDER
1. By means of a sucking away bottle pump out from a tank of a hydraulic brake drive a brake liquid to level about 10 mm.
The prevention

Do not empty completely a tank that air has not got to brake system.


2. Fill with a new brake liquid a tank to a mark "max".
3. Pull on the right back support of a disk brake a pure hose over the valve сапуна, substitute a suitable vessel.
4. Charge to the assistant to squeeze out some times a brake pedal until it will be created противодавление. Charge to squeeze out a brake pedal, simultaneously open the valve сапуна and leave to follow a brake liquid through a transparent hose. Close the valve сапуна if the pedal adjoins the basis of a bearing body, remove a foot from a pedal. This operation repeat (about 10 times) on each valve сапуна until already new brake liquid will start to act. The new brake liquid can be defined on more light colouring.
5. Close the valve сапуна, fill a tank with a new brake liquid.
6. As pump out an old brake liquid from other supports of disk brakes.
The prevention

In any case the lowered brake liquid should be transparent and not contain vials.

Old brake liquid hand over as спецотходы.
