    The unit on my 1995 f355 is not holding pressure. Does anyone know of a shop that can rebuild these units?
    Part #70000768 (this is the part with the reservoir on top)

    There is absolutely no one that will rebuild the TEVES master cylinder. You are out of luck. There is no rebuilt kit, either. The best you can do is to buy used ones from ebay, with a return guaranty if it does not work.

    This.....seems like a problem. These things cant last forever and all of our cars are either approaching or passed 30 years old.

    Ford super coupe have the same units. Although they are also very hard to locate. Maybe try and hit up the Ford forums for some hints.

    Do we know if maybe the accumulator is pooched
    You could replace that fairly cheap just like we do on our F1s

    until recently even though Watson said what a big difference his made the sceptic in me was not totally convinced but changing mine did the exact same as his
    And made a huge difference.
    Is it possible the pressure accumulator is not helping??

    Maybe the op can see the right side piece leaking?

    I am not near the car to inspect...it is at the dealership. They had the ABS pump rebuilt but now I am told the issue is with the master cylinder unit and they are currently looking for a solution. Yes I agree this could be a future problem if there is no rebuild kit as the few replacements that I have been able to locate are very expensive!

    I don't see it as so much of problem but rather a "capitalistic" opportunity. Come on aftermarket suppliers, step up and fill the need. ;)
