Reply to "Pressure Differenial Valve replacement"

"This subject has come up before and other have tried to perpetuate the myth that the shuttle valve closes off flow to the siide that loses pressure. I've cut open several of these valves and they all are machined down on the ends so that fluid will pass right on by. Forest".

My problem with mine is that the threads in the port that goes to the rear circuit are stripped. I called Dennis at PP. He said do away with it. Install a standard peddle switch for the brake lights. I am still not clear on how to then set off the red light on the dash. But by the time you see the red light you already know the brakes are gone.
