That " DO NOT TRY IT!" note about not trying to do your own installation or adjustments on the brake pads yourself is just......stupid.... What's the point of providing the instruction sheet for the brake pads then??
I'm sure putting that notice on the instructions was driven by their company lawyers, but it just reinforces the non-self reliance and responsibilty for ourselves and our actions. I didn't think it was that bad already back then but I guess it was......

BTW, are the finned Mathauser brakes holders/pads hard to find and expensive these days? I might consider using them on my early 70's bike project in place of the overpriced OEM pads that I need to find for the Campy NR calipers on bike, which are so crazy expensive out there if you find them.
