They are self adjusting. Some sdjust when backing up and hitting the brakes and some by using the parking brake. You can also adjust them by removing the rear drums.

i set the parking brake on my 2002 f-350 and it does not hold. I havent found where to adjust it on the truck. Can I adjust it or do I need to take it to a repair shop?
They are self adjusting. You don't have to adjust them. Problem is the wear limit on the drum is only 1mm. When worn to the limit the adjusters don't work.
