Another clutch not completely disengaging thread

3/8” travel,thats it?
Releasing bleeder and pushing slave in will it go further?
If the slave only travels 3/8” there is something wrong with it.

I dont care for hyd clutches, as i have had my share of grief with them too.
Vacum pump sealed to master resevoir and just pulled vacum,it retracted slave and extracted all of the air.
Manual bleeding =gravity wont bleed it. Resevoir passes through to slave and master can remain aireated.
