9.3. Pumping of hydraulic system of the drive of coupling

Any hydraulic system works normally if air is removed from it.

The liquid used in the hydraulic drive dissolves paint and plastic therefore at hit of liquid on a paint and varnish covering of the car wash out its large number waters.

During removal of air add only pure liquid recommended by the manufacturer.

The recommended liquid: SAE J1703 (DOT3).

 PERFORMANCE ORDER

  1. On the cylinder of switching off of coupling weaken the union of pumping and attach to it a hose. Arrange other end of a hose in the 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 out the air from hydraulic system. Tighten the union of pumping and release a coupling pedal.
  4. Repeat operations until there is a brake fluid without vials of air.

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