Just to veirfy, I have a 65 Nova. It has a single hose over the rear end feeding My rear drums. Those drums kept locking up and I knew they were dragging. So First thing I did was replace everything, replaced the brake hose over the rear end, brake cylinders, shoes, springs, and finally the whole front to rear brake lines. No dragging now. The rubber hose was original (Calif car) and was real cracked.
Its cheap insurance to do this.
