My rear brake drum has seen extensive internal rust, resulting in very deep and wide rust pitting on the braking surface. The exterior is actually in great shape. As drums are a rare find, has anyone experimented with reconditioning of the friction surface? I'm feeling the two options would be a sleeve insert or welding up and remachining to original diameter.
Welding sounds very tricky due to the potential for warping or deformation, making reinstallation of the sprocket a problem, among other possible issues, such as just keeping it round.
These drums aren't thick to begin with, machining what is left to a smooth surface would thin it to a dangerous level, in my opinion. So, has anyone done anything creative to bring a rear drum back?
