Boot failed and piston is a bit sticky in the bore so brake drags. Can I turn the piston out, clean and replace the seal and get it screwed together again with out a big hassle? Piston does turn but have not turned it way out till I know if it will screw together. Thanks

It requires some special tools to assemble them. They are a real pain the butt. You have to apply pressure while turning them - a modified C clamp sort of affair. The parking brake mechanism makes them difficult to assemble due to the spring pressure. I would look for a good used one that only needs a boot.
