    master cylinder

    I have a series 3 dual cylinder and the tank seem to have deteriorated by the the sun UV-turning into dust-the cap is gone and the tank is developing weakness ,also from UV. The MC was replaced about 4 years ago,not that old,but this will be a continual issue since the tank is sort of exposed. Question,is there a metal tank replacement MC,or has anyone fabricated something ?

    You may want to try the MC from a 1985 LTD or early dodge dakota. My understanding its the ford requires a slight mod to the pushrod, but has a metal reservoir. I think the ssis is a direct swap. The bore it slightly larger so would give a stiffer pedal. Im converting from single circuit to dual power and going to try the dakota MC since its like $40. The LTD one is $25, but I suck at fabricating.

      Don't have an answer for you, I'm afraid, but I'm curious how your brake MC is being exposed to so much UV light...Is the bonnet off?

        Not sure,I guess living in Florida is not kind to plastics.The clutch is also turning to dust but less so.

          the first one lasted this long 30+years, would expect replacement to also.
          food for thought

            Dual Question

            Is there an upgrade to the III series brakes to make it a dual master cylinder? Can this be put into my IIa 6 cylinder 109? My series III 1974 has all new brake upgreades and I was going to sell it as it needs a frame. But it has a engine, tranny and overdrive work and all new brake upgrades so I can swap into my IIa. Thoughts?
