It uses a small control signal from the foot valve to rapidly fill and exhaust the brake chambers on axles or trailers directly from the supply reservoir, reducing brake lag. It is commonly replaced when the valve leaks, fails to apply or release properly, or during a brake system overhaul. This aftermarket unit directly replaces Bendix 289395 and various Mack, Volvo, Freightliner, and Navistar part numbers.
