I got the dreaded "Brake Failure" error message last week, it showed up at start up without touching the brake or the emergency brake being enabled. I checked the tank, its filled to the top, then took it back to the local dealer. Two days of brake bleeding and now they say it needs a master cylinder, by the way the bike is a 2008 with 5k miles. The bike had no reduction of brake pedal or stopping power, Does this sound right or is the dealer blowing smoke.
