[DeTomaso] rear brake options?

[Rob Dumoulin]

I added the manual proportioning valve and two gauges too (see pic), but
came to realize that I don't need the valve after all and my fronts are
always getting full pressure. That is when I starting thinking that if I
improved the backs, I could switch the valve to step down the backs instead
of the fronts.
