Re: Re-installing rear brake drums

Still no luck. I completely released the hand brake tension at the equalizer (fully slack) and made sure that the rear service brakes were adjusted and then took her for a spin with the exact same results as before: grinding at braking speeds of 25-30 mph or above. The braking behavior was normal and pulled the car down steady and straight.
My thinking in leaving the hand brake essentially disconnected was to isolate potential mis-adjustment in the hand brake and ensure that nothing would impede the shoes from seating on the anchor pin. And then I hoped for the best but to no avail.
Attached are pictures that I took after my latest test drive. You can see the "polished" edges of the shoes with the heaviest contact occurring at the bottom of the secondary shoe and lighter contact at the top of the primary shoe.
The second picture shows the "polished" rivets on the underside of the drum. These points of contact do not seem to be getting any larger, if that makes a difference.
Again, I'm open to any thoughts. The shoes are probably the next suspect although I'm not sure how to identify a slight twist as they pass a visual inspection. After that, I suppose looking at the drum for warp is next.
