Thanks Tom - good point. I will order the centering tool today and report back soon. Thanks again for all your advice and council.

Forgot to ask - what is the best way to see if the drums are out of round and by how much. Should I take them to a parts store that turns them down??

Unless you see a flat spot on the drop, where it fell off a jack or the wheel fell off while driving down the road, I would just assume the drums are round. My 29 Tudor have a very bad pulse in the brake pedal, so I knew one of the drums was bad. As soon as I saw the flat spot on the edge of the rolled lip, I knew that was the problem drum. I swapped it with a good drum and all was well.

Look at the rolled lip right where it leaves the braking surface. If it's a nice smooth transition, then you can bet the drum has never been turned. If it has a line from being cut, that will be easy to see, and the sharper the transition, the more has been cut from the drum.

I have used the Les Andrews, notched board approach on two cars. My town sedan with cast iron drums stops on a dime now. My roadster, with steel drums, stops much better since I adjusted them using that method, but nothing like the sedan. I am going to get some cast iron drums. In reading the service bulletins, Les's method is very similar to what the Ford Service Bulletins suggest, so I think that is a pretty good method to use. All that said, there can be many factors contributing, as previous comments have shared.
