Air in the clutch hydraulics is readily apparent by the clutch pedal being soft and the clutch not releasing. If the clutch releases and the pedal is firm, there is no air problem. When the master cylinder is home, the port to the reservoir is open. There is no pressure or vacuum unless something is clogged.
