Replacing the wheel cylinder you only really need a 10mm open end wrench or (preferred not required) a brake line wrench. I also used a wrench (I *think* its also 10mm but not 100%) and not a socket on the bolts that hold the cylinder on because of the lack of room back there. Also, soak the lines in penetrating oil before you try to remove them. For cleaning the drum itself, nothing more than a can of spray brake cleaner and a rag, it might stink more but wont leave residue.

If your have more than 1 car with drums. The best thing to get is, if you don't have one a drum brake spring tool. So many cylinders new or old are lost due to people slipping with pliers or screw drivers attempting to pry springs into place. <img src="/forums/images/graemlins/shiner.gif" alt="" />

Edit, I don't want to go off topic. But is your garage floor real tile? How did you jack the rear wheel off the ground without cracking it? <img src="/forums/images/graemlins/lol.gif" alt="" /> I would love to have a tile floor for easy cleanup, but I would have to install a lift in my garage to keep from breaking it. <img src="/forums/images/graemlins/lol.gif" alt="" />
