Thanks for your response guys ealier,
But I just had one more question I read on an article online that "The best place to install a brake proportioning valve is after the distribution block. DO NOT INSTALL IT BETWEEN THE DISTRIBUTION BLOCK AND THE MASTER. You wil not able to get a hard pedal. Any where after the disribution block and before the rear flex house." Is this true?

I have heard that you can put it before and after but i dont know now and not sure where to put it.
So my question is does the adjustable prop valve go before the distribution block or after.

Have you heard this or had any problems for those guys who put their's between the master and the distribution block.

its a 67 chevelle and I did a conversion from front drum to disk.

Gome. I think I am beginning to understand the confusion. When I bought my set from SSB, I got a similar answer to my question where to put the adj. prop. valve. They actually faxed me a drawing in which the word "distribution block" was used (but with 5 connections). This confused me then too, but looking it over again to answer your question I now realize they must have meant "combination valve".

Back to your article now. If you read it again and substitute "distribution block" with combination valve, it will probably makes sense all of a sudden.

A plain distribution block in the real sense should be nothing more than a transparent connection between all of the lines connected to it. You could put the prop. valve in front of this.

(To back this up : on top of the rear axle there is another - true - distribution block to serve both left and right drum and your adj. prop. valve will be in front of this - speaking front to rear -).

But when a combination valve is used, you must put the adj. prop. valve after this.

Hope this helps.

Thanks Rusty!

this is the order, booster, mc, proportioning valve, distribution block (divides right and left sides), it's that simple, i also have an adjustable valve on mine but it's for just the rear's (disks) a proportioning valve just splits front/rear pressure, and lets you know if there is more pressure in 1 or the other, now im assuming your has a 2 section Mc, for front and back not just the single.

Yeh, I think the combination valve/distibution block thing can be a bit confusing also.

I sounds like you got your brakes from the same people I got mine from. Stainless Steel Brakes Co, sent me my brake kit and the instructions stated that I should not install the prop valve before the distibution block. I called them about this and they clarified that as long as the distribution block is not a combination valve It will not matter.

If your car is an original drum car then the distribution block on the frame rail is probably not a combination valve.

Anyway, I have mine routed as follows. Master cylinder then adjustable prop valve then distribution block. It seems to work very well.
