clutch hydrolics problem

[Konstantin Bogach]

Clutch pedal sank.  No visula leak in slave cylinder, small leak from
master (always was there).  After reading archives I diagnosed the
problem as bad master cylinder: goes bad more often, does not leak. I've
read that slave leaks outside but master usually leaks internally.
Replaced MC today. Bleeded using hand pump and second pair of hands (air
did not go inside on intake stroke).  I saw air bubles at the very
beginning then steady fluid about  1/3 liter.  Tighten valve, tried
clutch pedal - does not return.
Suspects:
1. Slave cylinder.
2. Depressed clutch pedal before filling brake fluid and ruined MC. (Did
it when fought with clevis pin, bolts and fitting).  Is MC really dry?

I supposed to go skiing tomorrow morning. Second car has brakes off. Bad
luck.
Could it be an air staying somewhere in MC?  I would appreciate any hint
or idea helping to resolve this problem.

Thanks.

Konstantin Bogach.
