It connects to two separate brake circuits and selects the higher pressure to apply the brakes, while activating the stop lamps when either circuit is pressurized. This valve is typically replaced when it leaks, fails to hold pressure, or the stoplight switch malfunctions. Note that the original DS-2 assembly is now obsolete and has been superseded by Bendix changeover kit K108143, which separates the double check valve and stoplight switch.
