7.2. Pumping of hydraulic system of a drive of coupling


During removal of air add only pure liquid recommended by the manufacturer. Do not mix brake liquids of various brands.

Brake liquid: SAE J1703 (DOT 3)

The liquid used in a hydraulic drive, dissolves paint and plastic therefore at liquid hit on a paint and varnish covering of the car wash out it a large amount of water.

1. Weaken the pumping union in the cylinder of switching off of coupling and attach to it a hose. Arrange other end of a hose in glass capacity of sufficient volume.

2. Slowly press a coupling pedal.
3. At the pressed pedal of coupling weaken the union of pumping and let the air out from hydraulic system. Tighten the union of pumping and release a coupling pedal.

4. Repeat operations until there will be a brake liquid without air vials.

The fast repeated pressing of a pedal of coupling in the field of B – C can lead to a pusher exit from the case of the cylinder of coupling during pumping. To press a pedal of coupling it is necessary only after its return to the top situation (And).
