I took the trashed original rear brake shoes for my 1950 4100 to a local truck/driveline business and they sent them off to one of their shops, and 3 days $250 later I had them back, and they looked great! But, 50 miles later one of the original bearing seals leaked gear oil on one, so after cleaning it didn't work out, I'll have to send that side back out, and hope I get the same lining material. I saved the other side by replacing both seals, which I should have done in the first place. Another expensive experience.
