But I'll answer what I can in the meantime and there are lots of other members that know more than I do. The rear port on the prop valve serves the rear brakes. The line coming from the prop valve for the front brakes should be 3/16" and it will run down to the tee and split into (2) 3/16" lines. Are you using a prop valve meant for a disc/drum combination? If so, you should just have one line from the prop valve for the front and one line for the rear.

Here's a link to a thread with a picture and some info: http://67-72chevytrucks.com/vboard/s...d.php?t=640142

If you don't have the right parts, I would call LMC and have them walk you through it. They're most likely Inline Tube brake lines. I got a full brake line set from GMCPauls (distributor for Inline Tube) and they sent the wrong front to rear line, so it's not uncommon for the wrong lines to be sent out.

Thanks MDPotter for your reply and for getting this organized!

I have a disc/drum prop valve - and based on what you said and some more thought I believe I have this solved. Again I think I jumped the gun on the posting.
However your information about the line size and the front and back lines off the prop valve helps immensely!

Thanks again! If I have anymore questions I will post on here. And thanks for the links! Just a huge credit to why this forum is so amazing.
