[Healeys] clutch hydraulics question

[Bob Haskell]

Listers,

If the clutch lever arm is disconnected from the slave cylinder push rod 
and the clutch pedal is pressed to the floor, the push rod is pushed to 
towards the rear of the car.  When the clutch pedal is released should 
the suction created in the hydraulic system pull the slave cylinder 
piston back in?  Or does the system rely on just the pressure plate 
springs to move the release bearing/lever arm/rod/piston back?

Cheers,
