    Hey guys, I know what's wrong with my braking now. It's in the booster. Checked the check valve and it's fine and installed correctly. Mechanic says plenty of vacuum at the booster. So the problems inside the booster. There are three nuts that hold it on from inside the bonnet. Is there a 4th nut? I think there is. Can someone tell me where it is? Is it accessed from under the dash?
    Thanks.

    4 nuts indeed. They are in a square sector so the 4 should be easily located. Not sure if the 4th is in the pedal case from the inside under the dash where your brake pedal goes up.

    Yes, 4 nut.
    Three easy...then You need fingers the size of a Sleestack to get to the forth.
    But, you have no choice.
    Good luck... BTW I have slightly used 3.2 booster for Sale.


    PM me..

    See.
    These things are pretty common, thus a reasonable price, the only Ferrari special part seems to be the 180 degree nipple.
    This one was working when it came off a 3.2.
    I wanted the 3.2 brake master cyl.
    Because, It is 25 mm. Bigger then my 23 mm 1981 unit. It matches my 3.2 front brakes with no pedal feel upset.

    PM me..
