how do you adjust the parking brake on a 2000 Suburban?

I couldn't find a model-year-specific procedure for that on line Hawk so i am going to refer you to the Chilton's for your Suburban. If you are lucky your local library may have that Chilton on their shelves and you can have your procedure for the cost of a few 25-cent copies. If not you can try your local parts store or book store. You can also try taking a cup of coffee to the service manager of your local Chevy dealer and hope he spills his guts. One other source of information is usually the parts counter guys are either your dealer or the local parts store. Those guys seem to know everything. Good luck!
