Hi guys. Check that both shoes are touching the large anchor pin at the top of the backing plate. Next, push the parking brake strut bar forward against the anti-rattle spring pressure. It should move at least an eighth of an inch. If neither of those are true, one of the rear parking brake cables is sticking in the partially-applied position.
Sometimes a shoe falls down into the groove around the backing plate when the hold-down spring is installed, then fails to get pulled up into position when the return spring is installed. You may need to use a small pry bar to pop the shoe out of the groove, then verify the frame is touching the anchor pin.
There are two unusual things I have seen beginner mechanics do. One fellow stuck the adjuster mechanism between the lower edges of the shoe frames, not on the webbing where they belong. You will see the notches in the ends of the adjusters are just wide enough to slip over the webbing. The lower parts of the frames are half as thick.
The same fellow installed the parking brake strut bar upside-down. They are shaped to provide clearance over the hub. He managed to get the drum on, but it made a grinding noise. That was on a Caravan. You will not get the drum to fit on some other models.
