The pilot reported that during the landing roll he applied the brakes, the airplane made a left turn, exited the left side of the runway, and impacted a hangar. A post-accident examination of the airplane by Federal Aviation Administration Air Safety Inspectors identified a failure of the airplane's master brake cylinder, revealing the master cylinder was leaking hydraulic fluid and no fluid was found in the brake system's reservoir. The airplane sustained substantial damage to the left wing.
The pilot reported there were no mechanical malfunctions or failures with the airplane prior to or during flight that would have precluded normal operation.
