Is it necessary to open the drums and clean it?
If yes, can I open the drum and spray all parts with brake cleaner?
What is more important is re-packing the bearings !
Simply spraying a whole can of brake cleaner on each will NOT make them "squeaky clean". You would have to disassemble and use a wire brush. There are also a few point behind the shoes that need lubrication and brake cleaner would remove that.
What kind of grease should I use lubricate the points behind the shoes?
