Master cylinder sizes

Hi Peter,

I can't say for the Mille, but on my SSD I use a 12mm unit from a Pantah. I changed it because I didn't like the original 15mm at all - very wooden, and I like to be able to feel the brakes coming on.

So Steve's 13mm unit may suit you.

Curiously, my Laverda Corsa has a 15mm master and is fine. Yet the only difference between the bikes is the floating discs on the Corsa; but I don't think that's the reason. I think it has more to do with the way the weight is distributed, and rider position. For example, I'm aware that I use mainly front brakes on the SSD, but the Corsa definiltey needs a little back brake as well - just to settle it.

Peter, DUCATI has standardized using a 13mm clutch since just after the F1. Some of the F1 have a 15mm clutch MC but most are 13.

You can;t lose with a new 13 and I have em in stock for you.

Now, was that Clutch or Brake? Ah, CLUTCH -- Oh, woops!

It is my understanding that the older round reservoir master cylinders (clutch & brake) that Brembo refers to as 15mm, will actually measure 15.875mm (that's 5/8in.). The newer rectangular m/c measure metric (12, 13, 15, 16mm)
