  • Champ dual MC install with Hydrovac

    I am going to install a dual chamber mc on a 62 champ pu with frame mounted hydrovac. How do I keep the dual(front-rear) line split in hooking up the hydrovac? it presently goes from the single chamber mc to the hydrovac and then tees into the single brake line that feeds both front and rear brakes.

    You either use the hydro for the front brakes or leave it out altogether. There's no way to use it on both circuits with a dual MC

      Bob is correct it is not possible to hook up a Stude hydrovac to a dual chamber MC and have power brakes front and back. You could have just power on one end or the other but I believe that would not be a safe way to run your brakes. There are quite a few threads on this subject since it seems to come up about once or twice a year. There are dual hydrovacs out there and some streetrod companies sell them but they are pricey. Ford and big Dodge trucks used dual hydrovacs into the 80s. The problem is that hydrovacs are between the MC and the brake calipers or cylinders, modern power boosters have the MC between the booster and calipers and/or cylinders.

      Couldn't you use a firewall mounted booster setup from a Lark on your Champ?

        That's what I was afraid of after looking it over. I guess for now I will go without the hydrovac hooked up.
        I'm assuming that I will need a non-boosted brake pedal?
        Thanks!

            does the Champ still have a frame mounted MC? If so, is there enough room to use a street rod style conventional vacuum/mechanical brake booster between the pedal and the new MC?

              The 62 champ is frame mounted. The 64 I have has hanging pedals.
              Here is a note from Jim Turner about the hydrovac--
              "If you use an original Hydrovac, you will only be able to boost the front brakes. But, a NEW hydrovac is available and set up for a dual M/C. It is from Midland Brake in Midland Texas. I checked awhile back, and they are about $800 for a brand new dual unit."
