Expert Reply:
For your generation of Chevy truck the issue you are having is almost always the third brake light fuse being blown. When this circuit is dead it also kills the brake controller wiring circuit that shows voltage when the brakes are applied.
Try pressing the brake and seeing if the third brake light above the cab comes on and replace the fuse as needed.
