Abstract
Hydraulic brake system between two vehicles provides for simultaneously braking both vehicles with equal intensity. An auxiliary master cylinder in the towing vehicle controls, through fluid pressure, four auxiliary brake cylinders, the middle two being part of a removable unit. The fourth auxiliary cylinder exerts fluid pressure during a towing mode, on the conventional brake system of the towed vehicle through a valve that shuts down the pressure exerted by the towed vehicle's master cylinder during the towing mode.
