Narrative:

I was taxiing for takeoff at an uncontrolled airport. While back taxiing I applied brakes to reverse course when the left brake failed causing me to run off the end of the runway and into the grass. I shut down both engines and inspected for damage. Since there was no apparent damage to the aircraft or runway lights, I started the engines and checked my brakes which were both working now, and taxied back on the runway. I again secured both engines and inspected for damage. Since there was no damage, I again started the engines, checked the brakes, and took off. I called the airport unicom and told them what had happened. In my opinion all my actions were in accordance with company procedures and good operating practices. However, in the future I will call my maintenance personnel and advise them of the incident before I resume flight.
