Brake Line setup

[biohazardbill]

I have purchased big brake kit front and rear for my 65 Suburban which have multi piston calipers. I have a new disc/disc master cylinder and prop valve.

So my question is about line sizes, I plan on making my own lines.

Should I run dual 1/4 inch lines from the M/C to the prop valve.

Then 3/16 to each side on the front to 3an Flexible lines
and for the rear run 1/4 to a 4an line to the T on the rear axle and split off 3/16 there to each side on the axle?

Thoughts/suggestions?
