"How To": 1999 - 2006 GMT800 Parking Brake Adjustment

The parking brake on your vehicle plays a vital role. Not only does it keep your vehicle from moving, it also relives your transmission and the rest of your drivetrain from holding the entire weight of the vehicle on its own. It is a key safety element, and maintenance on it should not be ignored. As the miles and years pass by, the tensioning cable for the parking brake can loosen up, resulting in a parking brake that doesn't do the one thing it's designed to do. Rather than immediately taking it to a shop to have everything replaced, try adjusting things instead to tighten it back up.
