Stuck rear calipers [redux]

[davidb01]

Didn't notice there's only one 2-pin adaptor in the bottom illustration.
That's the one I have.  Contact them for the p/n, since not enough info in
illustration.

There's also Lisle Tool Corp; see
http://www.lislecorp.com/tools/catalog/brakes/index.htm

* 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
