I have used Carpimoto in Italy for some bits for my M600 - excellent service and great prices for genuine Brembo parts. I bought rear brake caliper, both masters, pads etc etc. They do other Ducati related stuff too apart from brake parts.
It was better pre Brexit, but even now, taking into account the VAT, it's still a good deal.
The only downer is you have to order over 130 quids worth if you live in the UK, the parts arrive sharpish and then about a month later you get a bill for the VAT from DHL.

Worth a look and 10 mins with a calculator!
