HOW do i get my frozen R calipers unstuck from my rotorz? Options

[Schump]

I have a '73 2.0 i'm parting out, and my rear calipers are uberfrozen to the newish rear rotors.
anyone have a good way to get the pistons to slide back through their original hard as hell rubber seals and unseat so they'll loosen up enough to remove the calipers?
i've already loosened the e brake adjustment nut and of course loosened the bleeders! (IMG:style_emoticons/default/WTF.gif)

Contrary to what might have been said elsewhere, those hard as hell rubber seals aren't holding the pistons out there. There's some corrosion on the sidewall that's holding them in place. My guess is the pads are sticking to the rotors as well.

"Loosened the e brake adjustment nut" could be a couple different things. Let's start there. I'm going to assume you mean the outer adjuster lock nut. Did you then turn in the outer adjuster? Once you loosen that lock nut you should be able to use a 4mm hex and turn the adjuster clockwise. That should pull the piston back in enough for you to free up the caliper.

Also, take the clips out of the pins and drive the pins out of the pads. That act alone may free up the pads enough for you to lift the assembly off the rotors.

Also "and of course loosened the bleeders!" is not a going to do much of anything for you in this case (except get brake fluid all over everything.) I'd tighten them puppies back up. (IMG:style_emoticons/default/wink.gif)
