Removal of air from hydrosystem


In repair trucks for removal of air from hydrosystem there is a special device. The standard way of removal of air from system is more low considered.
Air from system leaves in the event that it was opened. To fill system follows only a fresh and pure liquid. It is impossible to use the flowed out liquid for this purpose.
The brake liquid is poisonous and has destroying influence on paint and varnish coverings. Therefore to address with a liquid follows cautiously.
At presence in system демпфирующего the cylinder air from it is issued before release of air from the working cylinder.

1. Lift and put on supports a forward part of the car.
2. Open a tank for check of level of a liquid. If necessary add a liquid to a mark "Max".
3. Remove a protective cap from the union of removal of air in the top part of a transmission.
4. Put on a transparent hose the union, its second end lower in a transparent vessel. In a vessel pour a liquid quantity. Check up, that the hose end always was below liquid level in a vessel.
5. In regular intervals press a coupling pedal. In the end of a pedal course strongly press on it. Open the union of removal of air. As soon as the coupling pedal will be pressed to a floor, close the union.
6. The described process repeat 10 - 15 times. Thus it is necessary to watch liquid level in a tank, adding a liquid. As soon as the liquid following from a hose will not contain air bubbles (in a vessel bubbles do not rise any more upwards), air is removed from system. The union tighten the moment of 9 Nanometers.
7. Check up liquid level in a tank. Check up coupling work as it is described in Section Check of coupling without removal.


There are brake liquids of different manufacturers. However it is necessary to adhere to a liquid recommended by firm Opel. This liquid well mixes up with a liquid still being in system.
