Tonight, in the middle of bleeding my new master cyl./slave cylinders, it dawned on me that I don't understand something about these van's I've always taken for granted - without some sort of "return spring" for the throwout level (on the bellhousing), what makes the slave cylinder return to its original "upright" position?

Is it simply the clutch pressure plate?  If so, why do other car manual transmissions/clutch have a return type spring on their system?

Thanks for group's insight - I'm always amazed by the good answers I receive from the Vanagon community.

Thanks
