63 valiant rear brakes

If you can pull the drums off, its probably not the brakes dragging. If you cant pull the drums off, back the adjuster out as far as you can and use a mallet to tap the drum off just dont beat on it. I have found the old lining broken and jammed in there more than once. They are a little complicated so take a few pics once you get the drum off so you remember where all the springs go and such. I hate drum brakes........but you gotta live with them in the rear if you own an older car.
