Actually to the best of my knowledge, there's no law on the books that prohibits use of asbestos in brake pads. They made a law, then repealed it. Probably understanding that some things - like asbestos - just don't have a good substitute.
I can't say with any certainty that they are asbestos. You could collect some of the dust it makes, and send it off to be analyzed. They sell asbestos testing kits at home depot. Otherwise, the youtube guy said somebody makes new ones, you might have to do some digging. Beyond that, they look like fairly simple circles. Find a local machinist and have them duplicated in some kind of plastic, either fiber reinforced plastic, or maybe abs. Not sure.
