In Cabin Brake Bias

[Legionnaire]

Excellent info Brad, thanks for reply, exactly what I wanted to see.

I was confused with mentioning about "T-ing" prop. valve into rear line - didn't understand that term. So I just plug bias valve inline between BMC and ABS unit, on the rear brake line. Or do I have to remove ABS unit in order to use prop. valve? What kind of maintenance, if any, is required for a prop valve?

I asked for pictures 'cause I wanted to see if factory hard brake lines are still in use with patrol BMC and prop valve. Judging by your pics the factory front line is reused with very little or no modifications at all. Rear seem to be bent and connected to the braided line that goes from prop valve - is this correct?
