Prop Valve pic please - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am in the process of putting `72 disc brakes on my `70. I need a pic of the proper way the lines run from the master cyl to the valve and which lines go where (front and back) from the prop valve. I'm pretty sure I have it right but don't want to bend lines until I'm sure. I know alot of you guys have done this. Thanks

Beuford, check out the install of my proportioning valve in my build thread in my signature (Blank Slate). There's a ton of pics of the setup in the thread. Hope this helps you out.

Do you have a C/10 or C/20? The lines are different.

Thanks alot. I printed the pic out so I don't have a senior moment and have to log back on to look again. I bought a new master cyl but I got the prop valve and center link and rotors from a donor truck. But they were off the truck already and I never saw how the lines were run. The rear line is for the front brakes right? Thank blkbeauty.

Bob the rear line is for the front brakes on a c/20 opposite on a c/10

Beuford · 03-30-2010, 04:17 PM

Thanks john. It is a C20.

Sorry about that Bob... wasn't aware it was a C20, but I'm glad to hear you got it figured out.
