"Ray, are you suggesting that the O P find and use toxic brakes shoes?"
Carl, when I built my '32 Ford roadster street rod braking was very poor with "organic" friction on the GM "Metric" caliper-Aspen/Volare rotor front and Ford 10" drum rear brakes. Asbestos friction was readily available on ebay from private parties. The asbestos difference was dramatic, almost like adding a booster. Like R12 refrigerant, asbestos friction materials are perfectly legal to own and sell privately, just not legal to manufacture. A quick check of ebay will show you how much asbestos friction is still out there and how inexpensive it is.
The OP may not know that and may find the information useful. Asbestos has the double whammy of a high friction coefficient and very minimal disc/drum wear. That works for me. If others don't want to use it, there are other options.
There is no end to what is considered toxic. I know that from my work as a geologist. Now copper in brake friction materials is blamed for lots of things. The same will happen to whatever replaces copper.
"Or are you suggesting he take his shoes to a non-existent shoe grinder?"
I had no trouble finding a place to get my shoes arc ground. I worked in an auto parts store as a kid and know how to do that job myself. If necessary I would have made my own arc grinder. It's a very simple device. My wood shaper could easily be adapted to do it.
If I'm not mistaken this is an information sharing forum and I make no apology for sharing information. It's not as if I were advocating something that would harm anyone.
