I watched the video from the one vendor that hawks their galvanized brake pad backing plate. Is there any real benefit? Or just in theory? Are OEMs galvanized and then painted? Any other brands? I feel Akebono to be high quality brake pads and could not see on their literature stating anything about the backing plate. For those changing a lot of brake pads in rust belt, how many have the pad material come off the backing plate? Solution looking for a problem?
