My vintage PUCH ran Mathuaser brake-pads for 24 YEARS! I recently swapped 'em for some Kool Stop salmon pads. Not because the Scott Mathauser ones were worn out - they are in excellent condition. I just wanted to preserve them as a part of bicycling-history. But as the Mathauser and the Kool Stop are made from the original formula cooked up by Mathauser, I don't see why they would wear out any faster.
Here are the original Scott Mathauser "SUPERBRAKE." Note the beveled, square washers that assists toe-in.
