Rear brakes on 66 dart NOISE and stutter?? HELP

I forgot to mention make sure the drums are actually true. This will require a brake lathe to check (or some sort of lathe or other centering device) You have to check the inside surface you cannot go by the outside. Also check runout on your axles. hell you might have a bent axle

One way to "get an idea" of drum surface runout with simple tools is..........Remove the drum, and carefully check stud to stud runout with a makeshift pointer, as well as runout on the center of the hub. You will want to clean, file, sandpaper, scrape etc

Then bolt the drum on "snug" with the inside facing OUT at you. Now you can use the axle itself as a makeshift lathe with a DIY pointer to check. This is not going to be that accurate, but it is better than nothing

Before you do that, though make sure there isn't something going on with the rear axle bearings themselves
