For some reason your parking brake rod isn't engaging with your front shoe---and it has to do that for anything to work. Get a piece of wood and a hammer, put the wood on top of the shoes and gently knock them downward so they fit correctly on the top and while doing that try to catch that brake rod in the cutout piece that engages the front shoe. Your pins will self-align. If this doesn't work for you, you'll need to remove the front shoe spring and shoe and re-install so that it catches that parking brake rod like you see in Phil's picture. I'm not certain what you did to get this, but if you get the rod and shoe connected right, you ought to be in tall cotton.
