Well ...... It was a classic case of supreme dumbassery on my part. Even after laying everything out in order, I somehow managed to swap the inner caliper halves - RH inner got bolted to LH outer, LH inner got bolted to RH outer. It was immediately evident as soon as I broke them apart. The two inner halves are identical except for the fluid passage hole, so maybe I got distracted during the critical moment of mating the parts, lol. It's all back together and bled. I'm chasing the elusive rock-solid lever, so for now I have the lever tied back against the throttle tube.

Just for any future reference - it is impossible for the piston to be all the way into the caliper, there is a small protrusion at the bottom of the caliper bore that holds it out far enough for fluid to get behind it.

Wow, good thing you took the calipers apart again before resorting to "drastic" measures to force the pistons out!

I never realised that the calipers could even go back together with mismatched halves.

Thank you for reporting back.
