High approach speed landed long. Turned onto wet grass at end of runway and slid into ditch. Unfamiliar with runway (.4)the pilot said that during a straight-in approach to the airport, he kept the airspeed at 110 knots, because the ride was very rough. The airplane's airspeed crossing the runway threshold was 100 knots. The airplane touched down about 1,000 feet down the runway. The pilot said that when he applied brake pressure, he noticed that he had no pressure on the left brake pedal. The pilot said that he pumped the pedal three times, and then reapplied the brakes. The airplane was now three quarters of the way down the runway. Just before reaching the displaced threshold, the pilot said that the airplane swerved to the right. The pilot swerved the airplane to the left in hopes of turning onto the grass. The airplane slid sideways in the grass crashing into a fence and coming to rest in a ditch. Examination of the runway revealed tire marks beginning a third of the way down from the approach end, and running evenly down the runway until departing the prepared surface. Tire impressions in the grass continued from the end of the runway, veering left, and endign at the spot where the airplane came to rest. Examination on the wreckage revealed no anomalies.
