Proportioning valve repair

[dostroupe]

Has anyone ever had on of these apart? Mine was stopped up to the back brakes. So I took it apart and cleaned it the best I could. My question is, is there a o ring on this plunger in that groove. It was nothing but white chalky stuff.

There are a couple very small o-rings inside the proportioning valve. Its been a while so I cant tell you exactly where. There is a company online that sells rebuild kits for them. Google it up and see if you can find them.

Man, you guys are great! I've never have had a problem with a proportioning valve in all my years of wrenching. I never would've thought there is all that much stuff to it, or even a rebuild kit for it. I guess I should have googled it first, but I thought nah no way. Thanks for the pictures @pishta, that's awesome.
