Do NOT break off the stars from the star wheel. With a straw on the aerosol can, squirt some penetrating oil into the threads of the adjuster. You'll have to estimate where it is. Work it back and forth until it comes loose. Then rotate it in the loosen direction. if you can't get them loose try pulling the drum off the shoes without loosening the adjustment. With only 3,000 miles on the drums this should be at least possible if not easy. With worn drums it's all but impossible to get the drums off without loosening the adjustment. I have done it but don't remember exactly how. You don't want to have to figure this out.
