I have the same problem. Just been back to the local dealer as the front brake fluid reservoir started leaking around the lid for absolutely no reason. Gasket replaced under warranty but both my front and rear brakes are squeaking, humming, noisy when pushing the bike around. Asked dealer to check it as I suspect warped discs on the front (bike only has 1900 miles). Dealer advised me that back of pads likely to be corroded and need cleaning and copper grease, but they wouldn't do it as a warranty item! Removed and cleaned the pads myself, no sign of any corrosion on front or rear pads, made sure callipers all clean and Pistons moving freely. All back together today but with the rain I haven't had a chance to ride the bike and see if it's cured the problem. This is my first Ducati, my first 16000 bike and I am not impressed so far. Yes it's a great bike, but I too have never warped discs on any bike - including owning a track day gsxr1000. I've had the dvt break down already (wireless key fob and steering lock issue) 600 miles for new, and Ducati seem to have included a free 'corrosion pack' that I don't remember ordering which seems to be starting to eat its way through most of the fasteners at the bottom of the bike! I'm not sure my Ducati ownership is going to last!
Mines in at the moment for a new set of discs under warranty"........................and heated grips...................and new sensor......................and new seats. Done 3500 miles and still love it, the rate it's going though it will be a new bike at the end of the warranty apart from engine and frame
Looking at the original post the pitting doesn't look like a rust issue to me. Any surface rust gets scrubbed off whenever you use your brakes. There is a little surface rust on the bits of the disc where the pad doesn't go and, to me, that shows the full extent of rust damage, i.e. nothing significant. I think there's some other process at work or it's possibly a manufacturing batch issue.
That same pitting issue has been around for some time though with Ducati discs, I had it on two different bikes, 848 and then 2012 1200 Multi. It was suggested at one stage that its water between the pads and the discs after washing/wet weather riding , that then reacts with the pad surface and disc surface creating the pitting. I actually dried the discs on the multi after each wash and it still happened, obviously i didn't sit there with a heat gun/hair dryer so to what extent you're meant to dry them i don't know, anymore than i did was simply too fiddly. It could change if swapping out the pads for something different, its the cheaper option of the two (pads/discs) so if i were back in the same boat id swap pads immediately after purchase and see how it goes.
That might be the explanation but it opens up another question - if it is a chemical reaction or similar caused by the combo of pads, discs and water then why does it only happen on some similar bikes? Also, I'd have thought it would be more widely known because lots of bikes use brembos. From the description it should definitely have happened to some of my bikes. It sounds like a bit of a fob-off to me but, then again, being wrong is something I excel at.
I honestly don't know, I admit it always sounded like a fob off but equally I'm not convinced that the quality of components used by Ducati are really that good. The brakes may say Brembo on them but I suspect that the discs and possibly pads are produced down to a price point, therefore not really a high quality item the brand name of Brembo would suggest. They're just a high margin item ducati can brand and resell for extra profits. Might have been different on the older models when ducati had to distinguish themselves apart from larger manufacturers, but nowadays it seems their quality is actually going backwards as opposed to forwards especially judging by the amount of faults and failures. The problem is that having owned loads of bikes it's only really shown it's face on a fairly high priced Ducati, I've even got a 2002 Yamaha R1 in the garage with the original discs fitted, they're spotless and I can assure you that's not had kid gloves treatment. The bmws I've had this last couple of years don't have issues with them either, or with the fixtures and fittings. I guess it's just another thing to add to the ownership of a ducati, some people will accept it and others may expect more from a 'perceived' premium product.
I had a quick google and didn't find much but this is from the AA's website: Surface pitting This used to be a reason for MOT test failure but data available following the introduction of the computerised MOT showed that too many cars were failing the test on 'brake discs pitted' even though this was not sufficient to weaken the disc. VOSA(Vehicle and Operator Services Agency) has subsequently revised the testers' manual and now discs should only fail the test if they have become 'seriously weakened'. If you only use your car a little, you may need to pay the rear discs special consideration – putting a wet car away in the garage means it's going to spend lots of time in a damp atmosphere for rust to set in. Surface corrosion or pitting of discs is not a 'fit for purpose' issue, nor a repair covered by warranty, rather it relates to type of use. While this seems to be concerned with MOTs, it does suggest a couple of things: 1 - that pitting is quite common. 2 - that yet again I have been talking bollox :Asshat: (although I'm still not completely convinced - straw to hang onto, anyone?).
