[NoVa-Corvairs] More brake bleeding nonsense

[novacc-list@corvair.org]

Re using vacuum ports on a car intake to bleed your brakes:  I'm afraid that I was the victim of a hoax.  The guy who suggested it was a bit too deadpan so I couldn't quite tell if he was talking out of his ass.  As it turns out, he was.  The BMW Bavaria email list I'm on is a far, far different animal than Virtual 'Vairs, and is the main reason why I invite only Corvair people to my home.

Bottom line: please don't use the vacuum ports on a car intake to bleed brakes.

I'll try bench bleeding the Corvair BMC, but I have to tell you that with the way the brake pedal flops without the least bit of resistance it's as if I have no master cylinder on there at all.
