Abstract
The present invention relates to a brake assembly for a vehicle having an air spring wherein a brake signal operates a brake cylinder of the vehicle. A proportioning valve, having its load responsive element disabled and being responsive to the brake signal, provides a proportioned brake signal to the brake cylinder. A switch, responsive to an air spring pressure signal selectively connects the brake signal to the brake cylinder. The present invention further relates to a method for retrofitting a brake system by disabling the load sensing element of a proportioning valve and inserting a switch in parallel with the proportioning valve.
