Honda is recalling 344-thousand of its Odyssey minivans because of a brake issue.  The company says a calibration error involving a sensor can cause unexpected braking when the driver is not pressing on the brake pedal.  The recall includes 2007 and 2008 Odyssey minivans.  There have been more than 20 reports of the braking issue in recent months, but no crashes or injuries. The sensor to fix the braking problem won't be available until the spring of 2014.  In the meantime, Honda says Odyssey owners should start their minivans with the wheels facing straight ahead.  The company also says tapping on the brake pedal can stop the self-braking action.
