From what I understand, the purpose of the floating discs is to stop them warping when they're in heavy use (ie in racing etc) where they can get very hot.
I did free mine up a few years back by putting a nut and bolt through the "float" bits, then using something (might have been brake cleaner or a small amount of penetrating oil or WD40, I really can't remember off hand) to ease them so when I turned the bolt, it would loosen them up.
But I haven't done that again since and, frankly, if you've not had problems in 20 years, I doubt you're going to have issues in the next 20!
