I fought and fought and fought aftermarket crap on our '63 9" front drums. They would drag, warp, get hot, go out of round and on and on.. I tried 3 different brands/style of drums and 3 different designs of shoes (yes if you look carefully shoe backing plates are designed differently). I FINALLY got a combo that worked and got in an emergency stopping situation and decided if the wife was driving she could have never pressed on the brake hard enough to stop as fast as I did and put disks on it. I still have the setups that worked on the shelf (with spindles). I am going to Spring Fling in Van Nuys next month and you can have them if you want them.
