摘要：
A towing hitch ball mount is adapted for telescopic use with a conventional towing hitch ball mounted receiver for automatically controlling the brakes of the towed vehicle. A pulley system having a flexible line or cable is mounted within the ball mount so that the cable is drawn into the ball mount as the towing vehicle is braked to simultaneously apply the brakes of the towed vehicle.
