Gee Mike -
I just made one of those brake bleeders using the GM cap as described in the site and bled my
Vanagon brakes using it.  The home-made blake bleeder described in the website was made for a BMW,
wasn't it?  And you said that we all need a 45 mm cap like is found on Audi, BMW, VW, etc.  True,
it need modifications as was mentioned in the site.  Could GM have made something useful/usable
for us Vanagonites?  The GM cap can't be used normally on the brake fluid reservoir - no provision
for a the brake fliid level sensor, but it works for a brake bleeder.
