10.5. Removal of air from a hydraulic path of the drive of switching off of coupling
Pumping of the hydraulic drive of switching off of system has to be carried out every time after removal of its components and also when liquid level in the tank falls so that air gets to the main cylinder. The principle of pumping the same, as used during removal of air from a brake path.

1. Fill in in the main cylinder fresh the DOT 3 brake fluid.
|
|
Do not reuse the liquid extorted from system, and also, the liquid, a long time stored in leaky closed container. |
2. The car also establish to Poddomkratta it on props, having provided normal access to the executive cylinder on a coupling dome.

3. Remove a dustproof cap and pull on the gate of pumping of the cylinder the end of the plastic hose suitable by the size (see an accompanying illustration). Lower the second end of a hose in the capacity which is partially filled with brake fluid with transparent walls. Track that the cut of a hose was entirely shipped in liquid.

4. Ask the assistant to squeeze out a pedal of coupling and to record it in we string situation. Open the gate of pumping and produce from the cylinder liquid in drain capacity. When the effluence of the liquid mixed with air bubbles stops, again densely tighten the gate and allow the assistant to release a pedal.
5. Continue pumping in the same manner until going out of the cylinder completely it is not exempted from air bubbles. Constantly you watch closely liquid level in the tank of the main cylinder, without allowing its excessive lowering dangerous by hit of air to the highway and data to zero all made efforts.
6. Having finished pumping, disconnect a hose and establish into place a dustproof cap. Lower the car on the earth and check serviceability of functioning of coupling.
