Narrative:

Aircraft commander took controls from other pilot when takeoff roll corrections went beyond acceptable limits. Pilot relinquished control but inadvertently remained on both brakes preventing the aircraft from obtaining sufficient takeoff speed and rendering rudder inputs ineffective. Aircraft commander decided to abort as aircraft left the north side of the east/west runway as the brakes began to fade because of overheating. Directional control was regained with rudder as beta was selected to stop the aircraft. Additionally two runway lights were shattered which severed the left brake line causing the aircraft to require towing to the FBO. The runway was temporarily switched to the north/south runway because of potential FOD. The aircraft was repaired on site and put back in service. The runway lights were repaired the same day. No injuries. A contributing factor was accumulated brake heat from previous landings.

Title: An Instructor rejected a takeoff when the pilot flying did not maintain directional control. The pilot flying remained on the brakes and the aircraft departed the runway striking lights and doing minor aircraft damage.
