WHILE TAXIING THE AIRCRAFT NEAR THE INTERSECTION OF TAXIWAYS CC AND A, THE PILOT ATTEMPTED TO SLOW THE AIRCRAFT DOWN BY APPLYING BOTH LEFT AND RIGHT BRAKES IN PREPARATION FOR A LEFT TURN TO THE DESIGNATED PARKING LOCATION ON THE RAMP. WHILE APPLYING BOTH BRAKES, THE PILOT STATED THE LEFT SIDE BRAKE GAVE OUT AND THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR.
