Narrative:
On takeoff roll approximately 70-75 KTS, a master caution light was observed for flight controls. The yaw damper had kicked off line. I decided to abort the takeoff as I had a slower commuter plane just taking off in front of us, which due to the distraction in the cockpit I lost sight of. Also we had an aircraft approximately 3 mi on final approach. Under the circumstances I felt it best to stop and clear the runway. The automatic rejected takeoff braking system was used and consideration for brake cooling was applied before continuing the flight. I did not return to the gate as no mechanical problem's occurred. The flight was completed without further incident.

Title: ABORTED TKOF AS MASTER CAUTION WARNING LIGHT COMES ON IN COCKPIT. USED AUTO-REJECTED TKOF BRAKING SYSTEM.
Narrative: ON TKOF ROLL APPROX 70-75 KTS, A MASTER CAUTION LIGHT WAS OBSERVED FOR FLT CONTROLS. THE YAW DAMPER HAD KICKED OFF LINE. I DECIDED TO ABORT THE TKOF AS I HAD A SLOWER COMMUTER PLANE JUST TAKING OFF IN FRONT OF US, WHICH DUE TO THE DISTR IN THE COCKPIT I LOST SIGHT OF. ALSO WE HAD AN ACFT APPROX 3 MI ON FINAL APCH. UNDER THE CIRCUMSTANCES I FELT IT BEST TO STOP AND CLEAR THE RWY. THE AUTOMATIC REJECTED TKOF BRAKING SYSTEM WAS USED AND CONSIDERATION FOR BRAKE COOLING WAS APPLIED BEFORE CONTINUING THE FLT. I DID NOT RETURN TO THE GATE AS NO MECHANICAL PROBLEM'S OCCURRED. THE FLT WAS COMPLETED WITHOUT FURTHER INCIDENT.
