ITEM NAME:   VALVE,BRAKE,PROPORT
DEFINITION:  A device designed to combine a warning light switch with a
             proportioning valve in a hydraulic brake system.  The warning switch
             activates the dashboard brake light in the event of pressure loss
             failure.  The proportioning valve reduces hydraulic pressure to the
             rear brakes to prevent rear wheel lockup during heavy brake
             application.
