Narrative:
I taxied out of the FBO at about XA05. After being cleared to taxi to the runway, picked up IFR clearance. After receiving takeoff clearance, started taxi to the runway. On the perpendicular taxiway to the runway, the left brake froze up, turning the aircraft abruptly to the left. Full right rudder and brake were applied. This straightened the aircraft out, but not before the left main tire was well into the soft shoulder.
