Have you read the first page of the thread yet? :p

edit: Murry has it?
The only thing I could think of on the firewall is the master cylinder!
I just drove to Sydney and back with a loaded trailer behind the County. This is the first time I've really given the new brakes a good workout. It was nice having brakes that grab harder the more you push the pedal instead of hoping you'll be able to stop :D

I recall some discussion a while back about the valve thingy on the firewall.
My recollection is that there are at least couple of different ones, but I don't recall if the function is the same.
Pretty sure the main purpose is to isolate a failed circuit so you still retain some braking, and that they aren't a proportioning valve so no effect when brakes are operating normally.
I've had a search and can't find the thread I'm thinking of. Think it was a discussion on functionality, and an issue with leaks.
Happy to be educated if I've got it wrong :)
Edit: And yes - mine is still connected.

I think you're talking about the shuttle valve sometimes called the brake balance valve. Unfortunatley it doesn't actually block the failed circuit, it only illuminates a warning light on the dash, which one hopes is still working.
Not everyone is all that technical, how many people have you known driving with their brakes metal to metal or the fan belts squealing without doing anything about it?
