JoeDude, the master cylinder is not the issue at this point although it may become one if the DOT 5 brake fluid deforms the rubber components within. Also with the new description, possibly the drums became rusty while sitting through the winter and now the shoes are grabby until the rust is polished off, one side being worse.
