My first guess is blown seals in the caliper as the rubber hose, and steel line are dry and intact, but the caliper is covered in brake fluid.
I'm just wondering why that would cause complete brake failure?
Comments or ideas???
Next thing is I'm going to open the bleeder screws and test each caliper to see if it is getting pressure when the pedal is pressed.

Well, nothing really. The redundancies in the system would prevent that. If you're panicking or the pedal went all the way to the floor and the system didn't have time to build pressure again, it might have felt that way. Otherwise as you've seen, our w123s have a dual circuit system –the reservoir has a baffle and the master cylinder, two channels.
Pretty scary though.
How on top of your brakes were you? When those seals blow, it's usually due to gunk in the system.
