Question Wilwood proportioning valve?

Hi Team,

I知 in the possess of up grading my brake system on my 69. I知 converting from manual disc/drum, to all Manual Disc. Below is a break down of the Wilwood package I ordered. My question is two part.

First question: The kit comes with an adjustable proportioning valve. Can I replace that valve using a 4 Wheel Disc Proportioning Valve / Distribution Block Combination Valve? http://www.mattsclassicbowties.com/c...n-us/d785.html

Second question: Should I still use the small valve mounted on the frame rail below the driver side door, or should I remove the valve and splice the lines together.

As always thank you!!

Re: Wilwood proportioning valve?

I used the Wilwood proportioning valve and I got rid of the distribution block entirely and just used a "T" on the frame rail. I have a solid line from the MC to the rear end. Here is the thread of my install:

Thanks Randy, Your pictures are a great resource and will be a tremendous help to me. I wanted to steer away from the adjustable valve. I understand they can be tricky to dial in. Correct me if I知 wrong.

Thanks, Joe

I have the prop valve inline but it is adjusted all the way in to give full pressure to the rears. I found that it worked best that way.

Re: Wilwood proportioning valve?

Randy, what size brake line are you running from your adjustable Proport valve to the rear of you car. 3/16??

Thanks, Joe

Re: Wilwood proportioning valve?

I am leery of the "combo" valves. There are a lot of factors that should go into the valving in that valve (of which I know little), such as vehicle weight, weight bias, tire sizes, rubber compound,caliper piston bore sizes, etc. To produce one valve that magically is right or correct seems a bit far fetched. Do you realize that most disc/drum 1st gen Camaros had NO proprtioning valve? Yet all of these aftermarket kits offer the magical valve that makes it all right. As I said, I'm leery. I'd way rather have an adjustable valve, which I do. That said, I run the sucker wide open.

To be honest I don't know for sure. I do know that they are stainless and a royal pain to re-flare.
