Hi Albert Looks like yo are doing a good job and you get the problems solved. Indeed, new parts are always suspect as they are not original Lancia. The father of Wainer Mariuzzo, my Italian colleague at the shop, was an Esatau driver. He worked for Fiat. His job was to pick up parts from suppliers. ...

That was the long answer.

The short answer is:
Do the test with one of the circuits empty and then the other circuit empty. If you can still brake without pushing the pedal throughthe floor, then you are ok.

Grazie Giovanni.
Good to see that material. Very nice.

I really look forward to see you again in Mondovi. As soon as the Corona thing is over we will drive to Mondovi again for some glasses of good Dolcetto.

The answer is not simple. Most Serie 1 cars have an 18 mm master cylinder. The amount of fluid the plungers displace per mm of travel is some 30% less than the displacement of the Series 2 mbc and about half the displacement of the mbc’s on Flavia and Flaminia. In hydraulics one calculates with surf...

Sure you can.

Best check the MBC on the table then.

When assembled with plungers but without container put it in a tray. Pour brake fluid in the rear cavity. See if it come out at the side.

mbc-s2.jpg Are you talking about the small hole roughly in the center? That hole is just before the cup. It fills the rear chamber. When you operate the rear plunger, the first thing it does is close that hole by moving forward. When the plunger moves home, it opens that hole so fluid can flow back...

Exactly. And also there is no hole to the compensation chamber of the rear plunger. If the thing is as on the drawing, it cannot work. There is more documentation, drawings, manuals etc from the early 70's which are no good. The feeling I often have is that the drawings were made by not fully inform...

The system at the bottom is similar in the Series 1 cars The Series 2 had silent blocs. First at the bottom only and later also at the top. Your bottom ones may have been converted to the silent blocs as the bottom ones often wear quicker. It is also possible to convert the top ones to silent blocs....

It is beautifully engineered.

Try Ferrari.
