Hi Tim,

I'm rebuilding a set of V8 calipers were the threaded rods did pop right
out.  However, I've got a 4kq rear caliper where the screwdriver trick just
doesn't work.

Its my thought that a slide hammer is the way to go.  It will require a
spare brake piston which I intend to get at the local wrecking yard.  You
drill a hole through the center of the piston and tap it to match the slide
hammer's shaft.  Then spin the modified piston onto the threaded rod until
it appears well engaged and chuck the caliper in a vise.  Then attach the
slide hammer and have at it, starting lightly at first.  Increase the
intensity till the rod comes out.

HTH,

-Tony
