I have had zero luck with 2 cars and front drums recently with the $hit parts you get today... I can almost guarantee you have the same problem I struggled with based on this. Can you reach through the wheel and get your finger on the drum? Drive it 10 minutes without touching the brakes. Bring it to a stop using downshifting and the parking brake. Get out and see if the drum on the side it pulls to is flaming hot. If so the adventure begins. The drums you get today are not round, period and contain half the metal that the OEM drum had. You have to get them turned right out of the box and the odds they will be round after you bolt them to the hubs is almost zero so the best bet is bolt them to the hubs (at the correct torque), mark the position so you can always put them on in the same orientation and take the hub and drum to have turned as a unit then always put them back together the exact same way. What is happening is the few mils the brakes retract are not enough for the out of round and the drums will scrape on the pads pushing them around on the float pins. When spinning the tire you will say "that not that bad" with the small scrape but it IS. It will overheat that side and that brake will get hot and start grabbing like a mother. I went through 3 different drums and 4 different brake shoes on the Dart before I finally got it working well but then decided the wife could not put enough pressure to stop in a panic stop and and went disks. The Coronet I ordered some NOS drums and have not tried to put them on yet so see if that works better. All I can say is the meat of the drum on the face where the bolt holes are IS TWICE as thick as the aftermarket crap we get today. I am anticipating these are round and will stay round because they are so much more beefy.
