    Auto parking brake release

    The original window sticker for my Country Squire has the auto-release parking brake listed as equipped but I've not been able to get it to work and thought it might not actually be there. Today while under the dash I saw that the parts are there which makes me believe that the mechanism just doesn't work anymore.
    I am looking for a part number or place to get a replacement.

    I don't have a part number but I can tell ya they are hard to find, working ones anyway. I have tried about 5 or 6 of the from yards I pulled and none of them worked. They tend to hiss when they're bad too. Also if you don't see a manual release lever clearly marked then you should be equipped. If you have auto release and it just doesn't work, then the manual release lever is tucked away and is a b**** to try to find sometimes.

      the valve probably failed, and/or was disconnected. Usually they leak so people plug the line rather than listen to it hiss and eat fuel economy.

        the horse shoe shaped valve might still available at parts places. The actuator is a dealer part and I got the last one 3 years ago and it died in 6 months.

        rock auto has 2 options:

        and
        http://www.rockauto.com/catalog/more...076&cc=1199471

        you can test the actuator by putting vacuum to it and see if it'll release the parking brake. If not, just plug the line from the firewall and forget about it.

          The leaking vacuum line damages fuel economy? By how much? Better go plug it then.

            My actuator actually got a rust hole in it and failed...found a nice junkyard one and it's worked well since. But the horseshoe switch can fail as well, best to get a hand vacuum pump and test the whole system piece by piece

              depends how bad the leak is, but any vacuum leak can mess with the fuel mix. The fuel metering system in these is entirely vacuum dependent, and anything that throws that off can have some effect. Its a small line and wouldn't do too much, but its definitely not going to help things any.

                  As usual, SLY and Gadget are all over this issue. These devices are a "weak link" in owning a Panther car. 100% of these leak at some time or another. Usually the vacuum lines break first and then the horseshoe shaped device on the steering column goes next. This is an odd dimension hard plastic line from the firewall to the shifter device on the column. Anyone found a good source for the plastic tubing??

                    I replace it with small rubber hose. The plastic stuff is too much of a pain to work with if its not pre-molded into the various shapes.

                      sorry to hi-jack but I am curious. there are clearly two parts that need to be replaced to fix this. One is a horseshow thing that goes over the steering column that you can buy at aparts store. What is the other part (and where in the car) that is hard to get??

                        The other part is a vacuum controlled release actuator..it's under the dash connected to the parking brake lever, behind it that is. Might be able to find a NOS one on ebay eventually…or grab a bunch from the junkyard. When i'm there next I'll probably grab 1 or 2

                          I wen tto the junkyard yesterday to take off the crescent valve and the cylindrical actuater things behind the parking brake release. Hopefully I did good! How do you test to see what i have in my car works good, whether it is a bad actuator or valve

                            I did some more investigating and found a wire disconnected, it turns on the parking brake light in the cluster.
                            The light is on no matter whether the brake is on or off, is that indicative of anything?

                              if the light is always on with that wire plugged in, the parking brake switch is bad.
