    It could be done with a hydraulic brake valve but, it would have to be manual (like the one TJones showed below) and, plumbed near the driver. I don't like the idea of the main hydraulic line to the brakes, running up to the dash to a valve, then back to the brakes on a street car. The opportunity for a leak or, damage is going up with each add on. This probably would not pass any on-highway laws.

    Now lets go racing. It's done all the time. In some forms of racing brake biasing valves are manually controlled, and usually close to the driver. Controlling the bias between front to rear is a "Driver Thing". The "Line Lock" is used in "Drag Racing" (but not cross dressing) to hold the front wheels locked at the starting line. On to the new generation and you see the "Drifter's" with a large 3 foot long lever yankin' on the rear brakes with a separate master cylinder hooked to the rear brakes and in some cases, an extra set of rear brakes!

    It can be done. From the rear brake line at the tee at the master cylinder, run the line to the dash to a manual shut off valve. Run the line from the valve back to the rear brake tee. If you stand on the brakes and close the valve, if there are no leaks, the brakes will be locked until you release them. Install a biasing valve instead of the lock and you are ready to track race!
