I landed on Runway XX at ZZZ and everything went smoothly until I applied the brakes. When I applied the brakes at about 15 kts. and the left brake seemed to lock up on me which caused the aircraft to spin to the left. I used full right rudder to try and counter the spin but the aircraft had already started to spin to the left. I went just off the side of the runway. I notified ATC that I was okay and would try and move the aircraft back onto the runway after I checked to make sure everything looked okay. It looked alright so I taxied the aircraft back to the ramp to make sure everything was okay. The aircraft is being looked over now.
C152 pilot reported a brake malfunction on landing that resulted in a runway excursion.
