    Hi Folks

    Can anyone point me in the right direction for a K/H proportioning valve re-build kit, or a new one. I have the original set-up on my 1971 Demon.

    Thanks

    Addressing your actual question, I tried to find such a thing several years ago, but all I came up with were dead links. It is possible that one could disassemble it, measure the sizes of the seals, and find equivalent replacements, but I haven't read about anyone doing so successfully. Maybe try searching the archives.

        Would 65-67 mustangs used something similar? They use very similar calipers, IIRC.

          Well, suit yourself.
          Tried to help, with my reply.
          All that i can tell you is, others have bought that "kit" used it, and didn't have any difficulties with it.
          That's how i saved the link, in my computers files.
          There have been many, numerous threads about your issue, in the past, so maybe do a search and see what comes up.

          No such thing as an "adjustable" proportioning valve on any of the A body line of cars, so i haven't got a clue what your talking about.

          If you do have a 71, and then the "factory" valve will be this one.
          And this valve was used from 70-76 on the A body line of cars.
          And i had lots of them in the past, that i used to put up for sale, on this site.
          So i think i know about these valves.

            Thanks for your input, I appreciate it. Yes that is the valve on my car. So the link that you supplied is a product that you have used on the above valve?

            Never said i personally used that valve.
            Never had a reason to buy, and use one.
            I stated "others" have used it from that vendor.

              No reason to get huffy. But I am telling you that 1967 cars, which I am familiar with (had 3), and as well as the 68 and 69 cars, use a different proportioning valve which is separate from the metering block/safety switch and has an adjustable knob on it. The picture you posted shows the later style with integrated proportioning valve. My understanding is that the kit you mentioned is correct for the block you showed. What I was unclear on was whether the change to the integrated style took place in 1970, or in 1973 when the brake rotors and calipers changed. If his 71 has that style, then it would be correct.

                I know that.
                The op isn't talking about a 67, 68, 69, A body car.
                But NO A body car had any type of "adjustable" valve on it.
                What the heck are you talking about?
                You better post a picture of what you think is a adjustable valve on an assembly line Mopar automobile.
                His heading states "71" and i replied with the link to that vendor accordingly.
                Don't know where you get the idea that i mentioned anything about a 67-69 disc brake car.

                  I thought I would throw this pic out there.
                  It shows the factory proportioning valve on my 69 Dart.

                    Correct.
                    But no "adjustable valve" like that member seems to be referring to?

                      Definitely look up the ford part, I bet its still available.
                      I've wondered about using one myself.

                      The op isn't asking about buying a replacement proportioning valve, if he can't find a "rebuilding kit"
                      He's inquiring, asking, about a "kit" so he can rebuild his existing one.

                      And besides, you can buy repop valves for a Mopar, that you don't have to purchase a Ford designed one.
                      But as of late it seems the repop ones for a Mopar tend to have defects, that they tend to be leaker's.
                      It's better to rebuild your old, existing one.
                      But i have no experience in ever trying, to use a Ford valve, on a Mopar automobile.
                      That's uncharted territory.

                        i just wondered if the rebuild parts or most of the parts are the same.... seals and such.

                        Yes, understood.
                        But you don't have to search out rebuild kits for a Ford designed prop valve, when there are parts out there from a few vendors, for the Mopar line of cars.

                          I think its called "stangersite" seems to show parts kits for the adjustable KH valve

                            Don't have any idea about this "stangersite" that you wrote.

                            But you don't seem to get it at all.
                            There is no such thing as an Adjustable Kelsey Hayes disc brake proportioning valve, for ANY kind of Mopar automobile.
                            That's just like trying to pass along fake news, that doesn't exist.

                            FYI
                            What showed up on GOOGLE typing in stangersite, has things to do about steering rebuilding, and nothing to do about brakes, or brake parts.

                              There was an adjustable valve that seems to have been used on some Fords and/or GMs that came with Kelsey Hayes 4 piston calipers. There's a photo of it in Mike Martin's book, and hence some might assume it was also an early factory Chrysler item.
                              This is all a side bar and I agree not really pertinant to the original question but worth addressing since its been raised.

                              Nope.
                              Sorry, but strongly disagree with with your statement that Ford, and or GM had an "Adjustable" brake proportioning valve on their line of automobiles.
                              Previously in my former life, before getting out of the trade, i was a wrenching mechanic for 30 years.
                              No such thing exists in any maintenance, repair, parts, manuals, showing anything in regards to adjustable valves.
                              And GM Did Not use Kelsey Hayes disc brakes on any of their cars.
                              FORD had 4 piston calipers from, 65-67 on their cars, that yes, were Kelsey Hayes, 4 piston, but after that they went to the single piston design.

                              You may be right and Martin was wrong. Its certainly easy enough to check if one has some mid 60s corvette and mustang books.
                              Only thing I have here that might show what was on those model is a 1970 Chiltons.

                              Well not surprisingly the Chilton is not helpful. It indicates Section 11 - Bendix disk - for Corvette, and Dart, and Mustang. So thats not correct. It also list section 13 - Kelsey Hayes - for Dart. That much is correct...

                              Anybody see anything "Adjustable" on an early Ford brake, proportioning valve?
                              Car manufacturer's didn't put anything like that on ANY of their cars.
                              Can you imagine some Bozo, messing around with something adjustable, on their car, and then getting into a wreck, with no brakes.
                              Car manufacturers didn't use anything like that, at all.
