Question to the VW gods

[ricksvw]

OK, I replaced my clutch front and rear cylinders about a year ago, I have been getting some spongy pedal that requires some pumping to get back on my 91 Vanagon. I did a vacuum bleed of the line and that didn't seem to fix the issue.

Now could this be from a bad brake cylinder? Should I look for a leak in the lines? if so, what areas are the best to start? And could it just be a crap replacement cylinder, do they go bad fast and how would I know if its the front or rear?

Thanks for any help, I know this is a shot in the dark...

little help on a Vanagon, but if a thorough bleeding doesn;t solve it (do all of them, not just ones you replaced maybe?) I'd go to the samba.com. they have the real veedub gurus there!
