I've gone through the service manual and I've been to a few sites and still
have this question: are the parking brake shoe adjusters supposed to be self
adjusting? I know about the cable and I've checked it on mine and the
ratchet was functioning properly. A two weeks ago I pulled the rotors off
and got to the pads. I cannot see how those adjusters are supposed to be
extended other than doing it manually with the rotor off. Is there some
trick to getting them to adjust without pulling the rotor?

By the way if you have to do this and get the shoes a little too tight and
you end up pulling the shoes off the plate when pulling off the rotor you
don't have to remove the axle (which is what the manual calls out) to
reinstall the shoes. You will need some safety wire, a scribe and a long
thin screwdriver plus another set of hands and it can be reinstalled without
further disassembly..
