I've tried everything I can think of. My brake locks up right when you put the brakes on. The drums are good, no marks, no digs. The wheel cylinder is new but didn't help. tried loosening everything and it still does it. right now everything under the drum is new, It is only the right side, so I don't think it can be the rubber line. I am starting to think that I might make the other side do the same thing and enter some drifting comp's or rally races.
