WHILE ATTEMPTING A FULL STOP LANDING, THE PILOT LOST DIRECTIONAL CONTROL WHEN THE LEFT BRAKE ASSEMBLY LOCKED AT TOUCHDOWN. THE AIRPLANE GROUND LOOPED AND VEERED OFF THE RIGHT SIDE OF THE RUNWAY. THE PILOT REPORTED EXPERIENCING A LOCKED LEFT BRAKE WHICH PREVENTED HIM FROM REGAINING DIRECTIONAL CONTROL. THE PILOT CONTENDED AFTER SOME RESEARCH THAT THE POOL OF WATER WHICH HE TAXIIED THROUGH WHILE TAXIING FOR TAKEOFF FROM GREENWOOD, MISSISSIPPI CAUSED THE BRAKE MATERIAL TO EXPAND ABOUT .090 INCHES. NORMAL CLEARANCE BETWEEN THE BRAKE DRUM AND THE BRAKE MATERIAL IS .010 INCHES. THIS EXPANSION CAUSED THE LEFT BRAKE TO LOCK, PREVENTING THE WHEEL FROM ROLLING FREELY.
Probable Cause: A LOCKED BRAKE WHICH PREVENTED THE PILOT FROM MAINTAINING DIRECTIONAL CONTROL DURING THE LANDING ROLL. THE BRAKE MATERIAL EXPANDED AFTER BECOMING WATER SOAKED WHILE TAXIING.
