Service Brake System message on your dash? If you have a full size truck or SUV made by General Motors (Chevrolet, GMC, Cadillac and perhaps even other vehicles made by GM) most likely the solder on the relay inside your "Electronic Brake Control Module" or EBCM has partially failed. The fix is easy. Getting the part off the car is the hardest part. Make sure to clean off those Torx screws as they are difficult to remove and any dirt will make it even more difficult.
