If you have the internal snap ring out, you already have the piston off and
are looking at a threaded rod sticking out of the bottom of the
cylinder.  That rod and its base are a machined fit into a recess in the
bottom of the cylinder.  It's tough to break the grip of the tight fit, but
I found using a pair of screwdrivers levering against the threads allowed
me to loosen up the grip and remove the threaded rod.  Below that is a
pocket with a little foot-ball shaped piece that fits into a groove
machined into the rod from the E-brake actuator lever.  That football keeps
the actuator from sliding out of the caliper.  With the threaded rod
removed, you can pull out the football and the E-brake actuator rod will
slide out of the caliper.
