PREVENTIONS
Never use repeatedly a liquid which has flowed out from a hydraulic drive of coupling.
The brake liquid гигроскопична, that is absorbs a moisture from air. Therefore a liquid, stored in open ware, it is not recommended to use long time.

At constant leaks of a liquid from a hydraulic drive or hit in hydraulic system of air define the reason and a place of leak and eliminate damage.
Removal of air from a hydraulic drive of coupling make as follows (in the course of prorolling watch that level of a brake liquid did not fall below the middle of a tank of brake system):
Remove a protective cap from the prorolling union on the working cylinder of coupling and clear the union.
Put on one end of a transparent hose the union of the prorolling, the second end of a hose lower in the glass vessel filled with a brake liquid on 5–7 see
The assistant should press a coupling pedal, and at the pressed pedal turn on on half of turn the prorolling union.
Continuing to press a pedal, supersede a liquid being in system together with air through a hose in capacity. After the pedal will reach extreme bottom position and вытекание liquids through a hose will stop, will screw the prorolling union home.
Repeat these operations, the air outlet from a hose will not stop yet.
Keeping a pedal in the pressed position, tighten the prorolling union against the stop and remove a hose from the prorolling union.
Wipe the union of prorolling and establish a protective cap.
