As long as the cheapo shoes fit OK go for it. I wouldn't screw with the cylinders unless they are leaking. Then you have to go through the whole bleeding process with the load sensor and all. It's not like the discs where the pistons change settings with new brakes, but thats me. If it ain't broke yet, leave it alone.
