  • Bleeding brake system

    55 commander....

    Is bleeding the brake system the same on this car as it would be on a modern car? I'm guessing it would be easiest to use a vacuum bleader as opposed to just pumping the crap outta them.

    I prefer a pressure bleeder, Motive Products makes a nice inexpensive unit. Unfortunately it doesn't come with a cap adapter for a Studebaker but it is fairly easy to make one if you have a spare cap laying around. just use a brass fitting with one end NPT and the other with a hose barb, drill and tap the cap so the fitting threads in, and JB-weld the vent hole. et voila. Probably easiest to do with a cap from a new MC as they are plastic not metal. Another option would be to use a cap from a disc brake car with the remote filler, that will work with no mods, just put a short piece of fuel line into it and clamp the hose to that, but those are becoming scarce.

    The reason I don't like pump bleeding is unless you have a brand new master cylinder it will often cause failure of the MC (not too far) down the road. Vacuum bleeding is good as well but IMHO you get the best results with a pressure bleeder. I've had one for a couple years now and have used the snot out of it.

    good luck,

      A vacuum bleeder is great for doing a fluid replacement every 1-2 years. But for a system that truly needs to be bled, I would want to have someone sitting in the car, if a power bleeder isn't available.

        Just start with the longest brake line first.
        You didn't say how modern...
        The new stuff has all the ABS solenoids that need to be switched open to bleed the brakes properly..

            if you do pump bleed put a scrap of 2x4 under the pedal to keep it from bottoming out. That may save the seals in your MC.

            If you've just replaced the MC, you can do whatever you want

            don't forget to change the fluid every 2 years from now on, that will keep everything hopefully clean and rust free. at least your hydraulics should last as long as your shoes, at a minimum.

            good luck

                General rule of thumb for the "old cars" is; bleed the R.R. first, then L.R., R.F and last, L.F. Most of the time it works very well. Ideally, use the power bleeder, it saves a bunch of work.

                  How does the "hillholder" effect the bleeding of the brakes ?

                    If you have a hydrovac, you can use an A/C pump to simulate engine vacuum, while you pump/bleed the brakes. You can have the engine idling, but that's your call.
                    I found this technique helps in quickly clearing out the hydro and getting the system done fast.

                      If you don't bleed the Hill Holder first you will probably never get all the air out of the system (I used two quarts of fluid and still couldn't get the pedal up before I figured that out). There is a bleeder ON TOP of the Hill Holder. I had to take my HH loose and let it down a bit to reach that [xx(][xx(] bleeder.

                        Anyone have an opinion on this? http://www.turnerbrake.com/images/new.ht4.jpg Im just getting started on a total restore but havent studied how that works with the hill holder.

                        On pressure bleeding - I have never done any car using that method but I avoided it as I thought the resivour would empty too quickly causing more running back and fourth.

                          What I'd love to have is one of thse jars the manual shows screwed into the top of the MC. I like using the vaccum system. Cleaned my systems out tout-suite.

                            Just run the rear brake line into your hill holder, then out to the brakes.

                              pressure bleeder does not empty reservoir, it pressurizes its own container with air and forces only fluid into the MC reservoir. You can run 2 qts. or more of fluid through the system without ever having to top off, it's a great time saver. I love mine. couldn't be without it.
