How to test a Proportioning Valve?

Is there a way to test a prop valve, or anybody know where I can buy one? I have a 70 K5 with front and rear drums. Thanks!

Re: How to test a Proportioning Valve?

Yes there is. Read through the post I started, which was due to a bad distribution block. In the thread is a link that will show you how to test it. I bought one new from Inline Tube, but it turned out to be defective. Once it was returned and replaced I had no problem. Good luck.
