Haven't driven the car in a while. Store it with the emergency brake on. Took it for a spin recently and the brakes were grabbing. I tried to cycle the brakes and the emergency brakes. Brakes still grabbed.
May be some rust build up in the drums, it will wear off, but if the emergency break cable is frozen up a bit, could cause this also. You could see by lifting the rear end up and spinning the rear wheels, they should rotate with a slight drag.
