first, make sure the brake fluid is full. If it is, take the truck to a nationally recognized parts store and have them scan it for codes. Let me know what you find. Also, most parts stores will scan for free, so it's no money out of your pocket. Most likely you have a sensor that has failed, and the only way to be sure is to scan the system.
