Abstract
A pressure control valve for use in vehicle hydraulic diagonal split brake systems. The valve includes two valve pistons which operate to limit the fluid pressure delivered to the rear wheel brakes relative to that delivered to the front wheel brakes. The valve also includes a failure warning mechanism having a switch actuating piston. In the event of a failure in one branch of the diagonal split brake system, the switch actuating piston operates to simultaneously preclude the two valve pistons from limiting the rear wheel brake pressure so that the rear wheel brake in the unfailed branch of the brake system can develop the maximum braking effort for vehicle emergency braking.
