73 Rear Brake Dragging
73 with right rear brake dragging. Smoked the pads. Pulled off the caliper and all four pistons are free. Parking brake is free. Car has 42,000 miles and all four calipers were replaced at about 30,000. Car has set alot in the last 8 years. Appears to have pressure in lines when car is not running. Any Ideas?

Agree , sounds like the hose isn't releasing the caliper. If they are over 5 years old replace them all, bleed the system every year if you store the car for a few months or every 2-3 years otherwise.

I had this exact problem!
It was the brake booster going out. For some reason it seemed it was not releasing the vacuum. Instead of working on a rebuild I just went and picked up a Brake Booster & Master Cylinder combo for about $130. I also had 2 calipers replaced before finding out that the booster was jacked up.
