Funny, the one thing I didn't do with the stock Brembo master was take out the caliper and measure the bore.
Have a look at this post on one of the Ducati boards, scroll down a wee bit to the chart there. Looks like 12mm and 13mm masters were used, and a description of whether they have silver or gold levers.
Hope this helps!
clutch is different to brake also.

Well spotted on the "12". I realise this is "sucking eggs" for a lot of people but Everyone should own a vernier digital caliper, it can measure internal and external on just about anything. Cost is £14gbp upwards. Stick one in your tool box.
"it may be a fast moving line in envelopes but to me it's stationary"
You absolutely right, I need a set of calipers. But even if did, I'm not sure which part to measure.
I emailed Steve at Bevel Heaven and he identified the size as 12mm and said that Brembo no longer makes these rebuild kits.
I did however find this on fleabay : http://www.ebay.com/itm/Ducati-Bremb...ZUovoO&vxp=mtr
Now I need to determine if this would actually work on this m/c
