Oh. First look at where the frames of the shoes contact the large anchor pin on top of the backing plate. If both shoes are not touching that pin, the parking brake cable is sticking partially applied or it is over-adjusted.
Next, look at the parking brake strut rod between the two shoes. You should be able to push it at least 1/16" against the anti-rattle spring with your thumb. If there is no free play, again, check the parking brake cable. If the cable is sluggish, use a pry bar to pry the lever that attaches to the rear shoe backwards on the bottom near where the cable is attached.
If you still can't find the problem, try to post a photo that includes the adjuster.
