Proper front brake line routing on '72

[joeydurango]

'72 K10, power disc/drum. New master cylinder and proportioning valve. When we put the new prop valve in, we realized there was an extra port that wasn't being used on the upper front of the valve (on the old one too) - basically, both front brakes are run off one line. It runs from the lower front port on the prop valve to a T-junction, then to both front calipers.

My questions are two: Shouldn't there be two distinct lines, one from each forward port to each front brake? And assuming that's the right way to do it, wouldn't that provide a lot more braking power, since with the single line/T-junction setup it's only moving half the amount of fluid to each caliper?

It works okay now. I just wonder how much better it would work with separate lines. Does anyone know from experience? Thanks!
