Quote: Just a shuttle valve in the distribution block to trip the warning light. It's designed to move to the low pressure side (front/rear) in case of a leak. It's normally self-centering as long as everything is working properly. It could be that it's stuck partially blocking the front line port, thus cutting the pressure.
This fits the existing theory and would explain the high firm pedal, if the fluid has no where to go the pedal would be great. Tommorrow I will remove and inspect the lines from the master to the splitter and the brake valve.
The valve is very simple, but be very careful. I've never had a Mopar one apart, but the Ford ones have lots of o-rings and springs and little pieces that can fly around the room.
