re
"But, since these are hydraulic, I don't know what you would adjust. Hmm"

I just wrote a big thing the other day addressing what is adjustable on
vanagon clutch hydraulics,
what commonly can wear and be a problem, how the whole thing is
self-adjusting at the slave cylinder ..
that the only adjustment is push rod length from clutch pedal to clutch
master cylinder etc. etc.,
