thanks for the info
I did it a little differently, the system was vented, but there is still a problem, because the clutch takes right at the floor. the clutch paw was replaced with a new one because the old one was worn at the point of contact with the thrust bearing. My opinion is too short the piston release of the clutch (the clutch was attached from the second car where everything was ok). Could it be the fault of the master cylinder itself?
I plan to put on a change from a second car, in which everything is ok, the entire hydraulic system is clutched - then everything will be clear whether the hydraulics or the mechanical clutch itself ...
