I've had this happen to me a few years ago...
I just loaded the arse end with about a ton of weight.. and did several 90-0 'break in' stops.
First stop I just let em barely drag.. and each one later got on them harder and harder.

Curious.. did you get ALL the rust inhibitor off the drums before installing? At least the contact area?

aftermarket brakes have to fit a myriad of different drum sizes.. ranging from stock brand new.. to a drum that may be at or even over max allowable.. and the only way to get em perfect.. is to either burn em in, or do like anoldbiker did.

strange about the differences you found in thickness of various brands of shoes! Did you ever find a set that is equal?

Your next step in my mind is to have the drums turned and see how out of round they are. Depending on how 'creative' you are and feel you could put the rear axle on jack stands, remove the wheels then pull the drums and put them back on backwards with four lug nuts holding them on. Make a stand that can sit on the floor and have a pointer that can slide in the drums without hitting anything. Start the truck and put it in drive. Make sure you are careful doing this!! Use the pointer to see how much run out there is. Like I said, even the thickness of a fingernail can cause a vibration.

She is still having the same issue. It sure sounds to me like you are going to have to find a place to true up the drums. Maybe the NAPA you got them at can help?

Napa said they would replace them or turn them if needed... I will give it a few hundred miles more before I do anything... I have NEVER had an issue like this ever doing brakes!! In our family, Dad and I have never taken our vehicles in to have the brakes done, we always did them ourselves!!( I have been helping Dad work on the cars since I was 3...(Did I mention I had the best Dad in the World??) Anyway, this set #'s 6&7 started off smooth as silk.. Put about 200 miles on them and slight chatter... The only thing I can figure is as they get heated they start to warp... Bad metal from china maybe??? ( Being that we in the US don't make any brake drums anymore )
