So, yet another cool vanagon dude, Alistair Bell, helps me out and
suggests that what I really need is a pressure bleeder for my brakes
instead of swapping out the relatives in my house that find it a pain
to keep pumping the brake pedal for me when I drain the brake system
of air.
I find this site.  Thanks!

I'm in the office now and can't remember whether the brake reservoir
had a tap on it.  I seem to remember that there might have been
something on the brake reservoir to hook a tube onto?  maybe wishful
thinking?  If not, do people have have a suggestion for an aftermarket
cap that I can use to hack in a tap?

Also, why are the Bus Depot ATE brake calipers so much cheaper than
other places?  $100 each for new ones... Is this for real?  I'm still
planning to reuse my current calipers and just spend $20 on the gasket
kit.  $20 does both sides, right?

Craig
