Good day turns bad, Master Cylinder? Options

[jfort]

finally get car all back together. Tach and shift light work. Clean it up for the triumphant, it all works, spin around the block. Car is running great. I'm flying down a country road with a smile on my face. This is what it's all about! Put on the breaks, I feel pedal "pop" and go to the floor. No brakes! Limp home. Reservoir is empty. Nothing at any caliper. A little fluid on garage floor under about the pedals. Master cylinder? I don't even know where it is, yet. Under gas tank? Behind pedal cluster? How does one get to the master cylinder? I am searching for my .pdf manual now. DAMN!

I pulled my aluminum calipers out of the box and had a look. Nothin' magick enough to warrant a picture ('side which my primary desktop computer woke up dead so I'm posting without half my image-processing tools...).

There's a 8- or 9" section of standard hard line screwed directly into the fitting on the side of the caliper. That runs up to the tab on the strut tube, where it connects to the flex line; I'm 100% certain I used standard 914 flex lines, 'cause I had them before I had the aluminum S calipers.

If that doesn't match your situation, perhaps a picture of what you're trying to run would help because (sorry) "I've never encountered that" either...
