Need help with/pics of brake lines/master to valve - The 1947 - Present Chevrolet & GMC Truck Message Board Network

$#@*&*@@$%#@!!!
I wish I'd gotten the whole setup from a half ton truck. 2 problems:
1. The prop. valve is set up opposite as my factory one
2. The lines from valve to master have metric fittings WTF!
stock - 69 C10, manual drums
put/putting in booster, master, and prop. valve from 71-72 C20

My neighbor is a Chevrolet mechanic so he will hopefully help me with the lines but does anyone have info/pics on how the prop. valve is supposed to go? The lines for front and rear in line up and fit one way so my plan is to put it in that way but I sure would like some help.

Any one have or willing to take some labeled pics on how this is supposed to go? Any one know where I can get tubing stock and fittings to make my own lines? This is crazy.

I sure wish I'd either
A. gotten the assembly intact from the yard or
B. had the money to get a new kit

Thanks a ton,
Jason

Do I read your post correctly? You are putting a prop valve from a
71 C 20 onto a drum brake setup? Or are you converting to discs?

I don't believe that I would use a prop valve on drum brakes. They were designed for equal pressure front and rear.

The local automotive parts store should be able to order rolls of tubing for you. Otherwise they have made up tubing in shorter
lengths.

Can't help on pics as we do not have a 69.

Ahh, sorry. I am converting to front discs. I got GMCPauls disc conversion (lovely!) and the booster/brackets/prop valve from the 3/4 ton (disc/drum) from a local yard.

I went to NAPA, Autozone, and O'Reilly's -- none had tubing rolls!

I am having no problems (so far) with any lines b/t the wheels and prop. valve but the ones b/t the damn valve and master are pissing me *%@$@@# off!
