I have never had any good luck with the automatic adjusters on drum brakes on any vehicle. All the brake hardware on this truck was replaced by me about 2 years ago. Everything was installed as per the official big $ GMC manuals. The threaded adjusters don't screw out to keep the shoes in position properly - I have to manually screw them into position. I've tried various lubricants on other vehicle adjusters, nothing on these current units except what came on them. Does anyone have an idea what lubricant would work best?
