If your p30 master crosses a Dorman M39309 it is not a step bore. I took one apart.

I wonder why the differential pressure switch is not activating making the brake light come on? Is there some thing in the rear part of the combination valve that is effecting pressure? It shouldn't.

Bad electrical connections, burned out bulb. Maybe he switch is stuck. If its that last one, he might end up replacing the combination valve anyway in the process of exorcising the demon.
