I can't understand how an electrical signal can prevent the parking brakes from kicking in due to low pressure. I believe that the parking brake is just an air pressure versus spring pressure balance--when the air pressure gets low, the springs just kick in and there is nothing we can do about it without more air pressure. But I could be wrong and thanks for the thought. I'll have to do some more tracing of wires.
