    Default Tredle Vac

    My car as converted to a dual master cylinder before I bought the var. The brakes are horrible, and I have had a quality shop working on it and we have decided that the factory knew best and want to move back to the Tredle Vac system and return to the factory spec's. The front brakes show little pressure till the end and then lock up, we have added a valve, but still no luck.

    My question is I have no core, so many won't sell the unit without a core. Is there a conversion to other like a T-Bird/Mercury or other Ford part that may not carry the extreme price tag. I still don't have a core but know that other part numbers may be more available so not an important for a core.

    Any advice is appreciated.

    I traded 2 treadle vacs to Barry Wolk a while back. You could ask him and see if he wants to sell one.

    I wish I did have a group of parts to trade. It may be a long shot; I have two large hides, Bridge of Weir in dark red that I over bought when I had the interior done that I won't be using. Overall, I have been trying to restore, reuse, and generally clean-up to original as much as possible! So, all serviceable parts have been reused. If you would consider selling one, I would be interested. I have been following your work, and I can share my vision of C56B2076 so you know the unit is going to a good home ! Please let me know if you would consider. Thank you!

    Make me an offer I can't refuse. I don't even know which internals they have. If you have the choice buy a refurbished sleeve valve unit over a poppet unit. The poppet type is too "grabby" for my tastes, but the car will have a vacuum leak every time you put your foot on the pedal at a light. You can hear and feel the change.

    Your offer is appropriate. I’ll open them both and send you the best of the two. If they’re not salvageable I’ll let you know.

    Only one of the vacuum chambers I got from Morgan was salvageable. Fortunately, I still had the chamber that Mad Scientist gave me 20 years ago.

    The early units were exposed zinc plated that rusted with the slightest scratch, likely the reason they painted over the zinc on later units. Due to interior imperfections I'm going to have the two good units heavy zinc-plated so I can sand imperfections out of the bore on my lathe.

    I have enough parts for two units, but I need these parts to complete them. One for you, and one for me. I tire of my car sounding so terrible at traffic lights when I depress the pedal my on my early sleeve valve T-V.

    All of the first day production photos show an unpainted T-V.
