Thanks guys. I've always had the mode of panicking (actually heat stroke in this case), then settle down and think about it logically.

I had seen the bleed screw but thought it was a bolt with a metal strap around it, as in 'don't remove'. As soon as I got back from my cool down, it became obvious. I'm not used to sideways bleed screws except on slave cylinders.

I'll add that my brake pedal was (hopefully past tense) going down two thirds of the way down. Not good for stop and go freeway traffic. Otherwise I'd be in my cool 90 degree shop with fans blowing on me while working on a client's car.

I still have the fronts to do. Not sure if either of you had read my brake caliper/pads post in Brakes/Suspension but in that case my MityVac didn't work. I finally ran across my one-way bleed valve and it seems to be working, at least on the rears.
