Brake Drum Sizes

During the process of repacking my front wheel bearings, I decided to note the size of my drums and brake linings. The drum is 12" and the shoes where right at 2 3/4" wide. Out of curiosity I looked at a few part places for replacements. No on seems to list this size for my truck. Is this a special size for the GVW # 7500 C20?

Re: Brake Drum Sizes

I believe that mine were also 12". Not sure where the 11.change diameter comes from. I think that that was a 6 lug thing? Not sure. Couldn't tell you now, since my drum brake components went bye-bye a few years for a disc brake setup.
