Changing from service operation to parking or emergency braking requires controlled spring-brake pressure, and the Bendix Air Brake Spring Brake Modulating Valve manages that transition in the pneumatic system. As service and parking conditions change, the valve coordinates air so the spring brakes can apply or release in the intended sequence. Because its job is tied to spring-brake operation rather than ordinary service delivery alone, application confirmation matters before substituting a standard relay valve in the same area. Within the matching spring-brake circuit, the Bendix K035737 becomes the valve that meters the apply-and-release behavior described above.
