Did you have normal pressure, then all of a sudden the pedal went to the floor? If so, I would suspect a sticking caliper piston. It was probably stuck, then midway through your braking, it popped free. Thus losing pedal pressure. Mine does the same every once in a while.

One way to check your pistons: Remove your calipers and take out the pads. You should be able to compress each piston with a set of channel locks (easily). If one is exceptionally hard to compress, it is likely the cause of your problem.
