Ok gang - I know the Vanagon calls for Dot 4 brake fluid but could one use
Dot 3 temporarily just to get a bus up and running to check that other
things are working properly? Maybe a very short test drive. Then bleed out
the Dot 3 and replace it with Dot 4 when it's time to drive on a regular
basis.

Thanks,
