There's also Lisle Tool Corp; see
* Specifically, "Rear Disc Brake Piston Tool (28300)" (cube-type); also the
piston tools illustrated on the very bottom of this same page. I purchased
one of these, but don't recall which one.

I've used a large C-clamp to apply pressure to the piston while turning
with water pump pliers (careful not to pinch the rubber boot with pliers
teeth--guaranteed to cause tears and tears). Opening the bleeder sometimes
makes compressing with the C-clamp easier. Usually, if you get it turning,
you can just keep turning. Can't say enough about how much easier moving
the piston back in is
