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..
