Seeing that they are 2 piece: did you split the calipers as part of the rebuild? If so: maybe something blocking the porting to the inner portion of the caliper? Is it possible that the inner halves are installed on the wrong sides thus preventing proper alignment of the porting? I'd highly doubt this would even be possible, but ya never know.

I'd be really surprised if the pistons could be bottomed out to the point where hydraulic fluid couldn't get behind them. You did exactly what I would've done by locking the outer pistons to isolate the inner ones. How did the lever feel in that case? Was the lever solid or did it go to the bar/squishy?

Never heard of a problem like this so I'm just throwing ideas out there - sorry can't help more!
