Narrative:

On sep/xa/98 approximately XX30 I was approaching runway 35 in carthage lake county airport, ms (25 NM northeast of jackson, ms) under squawk code VFR from jan approach on 123.9 frequency. As I was landing the aircraft, the left brake locked up and the plane skidded to the left off of the runway. To bring the plane under control, I lifted the nose up and applied full brakes until the plane stopped. The ELT came on. I shut down the engine and inspected the plane. The plane didn't have any damage. I taxied the plane back on the runway and onto the local ramp. I checked the brakes on the plane and everything seemed to be working properly. I called operations from the local pay phone to inform them of the situation. I requested information on how to handle this matter. I was told to return to the madison airport (nbo), ms, if everything was in line. They gave me a new squawk code and I proceeded to madison airport (nbo), ms. When landing, the left brake locked up again. The plane skidded to the left for the second time. I followed the same procedure as I did at carthage airport earlier that same day and stopped the plane with no damage occurring.
