Finding Huck brakes for 3600's and 3800's can be a bit tricky. John had to have the brake shoes relined on his 3800 pickup, and the first try didn't take- - - -the bonding glue on the linings failed and the linings came off the shoes. I think the rebuilder ended up doing some riveting on the second attempt. If the shoes aren't worn or damaged, don't discard them. They can have the friction material replaced.
