It's frustrating, I know. If your positive the throughout bearing is pushing the prassure plate back when you press the clutch down, then there isn't a whole lot you can do. On some older models of slave cylinders there is adjustment of the rod that pushes on the arm that moves the troughout bearing. It gets adjusted when the clutch is old and needs to be adjusted back when you put a new set in it. This would be the last thing to check. Good luck, hope you get it figured out. - Matt
