ABSTRACT:
A valve assembly for selectively controlling application of a spring brake in a truck brake system having primary and secondary circuits is provided. A spring brake valve is modified to incorporate a balance piston having an integral quick release valve. This reduces the number of components, complexity, and service problems while maintaining all of the advantages associated with monitoring the function of the primary circuit.
