You probably do not have self adjusting brakes on the 4400 axle.
The way to check is to crawl under the unit and look through the slots in the brake's backing plate after removing the rubber cap, if they were installed. Self adjusting have a spring wrapped around the shaft of the star wheel. Non-self adjusting have a spring "along side" the star wheel.
eTrailer has some images that show the difference.
