proportioning valve has 2 front outlets?
 

My new disc/disc proportioning valve has 2 front brake outlets. The one I took off only has 1 and uses a splitter on the cross member. Is there any reason I can't run the way it was set up and plug one of those outlets? Or do I need to use both outlets on the proportioning valve because it has two?

My disc/drum combination valve came with a plug in the upper outlet, and that's the way I installed it. I'm assuming this arrangement would also be fine for your disc/disc setup.

DOH!!! I should have read the step-by- step instructions. It actually says "An alternative plumbing method is to plug off the top front line and have the bottom front line go to a "T" fitting."

I'm really not that smart. LOL.

Instructions?...We don't need no stinking instructions! Lol!:lol:

That has always been my philosophy, but when it goes wrong and I do read them and the answer is obvious I really feel stupid. "Oh sure that would work!" LOL

So I am a few months away from getting the cab back on and connecting the brake lines.

My question is do most of you use a 'T' for the front brakes or use both ports for the front brakes?

Re: proportioning valve has 2 front outlets?
 

Since my 72 "stock" lines are "T", I chose to just leave them that way and use the plug on other front port of PV.

My 67 (Camaro) with separate lines, I use both.

If you are making your own lines, using both is not a problem.

I have never seen three brake lines coming from the distribution valve/block.
Only ever see two, the front, and rear lines.

I just rebent my lines from the dis-block. The hydroboost setup only has 3/16” line connections, and mine were 1/4”.
The front 1/4” line went down to the crossmember, where it splits off to two separate 3/16” lines. I just replaced the tee that was 3/16, 1/4, 3/16 with one that had all three ports in 3/16”. (Tubing size)
