My Dodge does the same. The rear drum brakes self-adjusters are not working. Try backing up and stopping suddenly and strongly, to a complete stop. It may require several attempts to get them to ratchet up to the proper adjustment. I've even had to remove the rear wheels to clean and lube the adjustment screws a couple times. But then, if you have all disc brakes ignore this post, as I have no experience with them.
