RF brake doesn't work, and it seems to drag too, but I can't get the wheel off to look at the brakes. I can get it to move outward ~1/4 inch but it seems to get hung up on the shoes. I can see the adjuster, which appears to be backed off to the minimum. (LF wheel came off easy so I've seen whats in there). I'm guessing that the wheel cylinder is frozen (out) but that's only a guess based on the position of the screw-adjuster and how its behaving.

Any ideas what I might do next? THANKS!
