I don't want to doubt your claims, Robert, but it is hard to believe you've done almost a quarter of a million kilometres on the original pads and shoes and they are only a quarter worn. If you're correct I'd say you're on track to set a world record. I'd be phoning the Guinness Book of Records and getting them prepared for a new entry. Seriously though, commercials do have different braking requirements from passenger cars. They have to carry loads and they are not expected to stop on a 5c piece, as we expect our passenger cars to do today. Also, commercial vehicle operators would not tolerate the wear rates of some passenger cars and there would be an outcry if their utes and vans chewed up brake linings like some passenger cars do.
