Regarding the bleeder screw, I was wondering if one couldn't mount some
kind of pressure valve in place of the screw that would work somewhat
like a one of those over-heating valves on a water heater.  To test
them, you lift up on the trigger and if it hisses, its working.  I
think something like that with a flexible hose routed down near the
lower part of the car would be nice for bleeding the system. 

Oh well, just thinking out loud....  :)
