For info, Yesterday visited my dealer to have my exhaust valve replaced and fuel sender. I mentioned my discs were warped again (already been replaced twice) and he said he had been to a european seminar (corsica i think, but could be wrong) and said there were lots of european dealers which had replaced "stacks" of discs on multis and diavels. One dealer said he had literally dozens sitting in his workshop! Now, the interesting part is, we are told we have the brakes from the panigale and my dealer told me we do not!!!! we have the calipers! the discs are not and all the dealers were talking about them being cheap chinese versions. panigales are not warping discs! just a heads up to check your discs mine is a 2016my 1200s. my dealer has another 2016my which is making th first signs of warped discs at 800 miles (funny noses when wheeling the bike!)
I was told that by my Dealer at the first service - and they continue to get slightly worse as miles move on. Happens worse when trundling around car parks or making ones way to the front of the queue at traffic lights. You do get some strange stares from the noise. Not good.
This is not a recent problem, why the hell do they continue to use crap discs, my 2012 hyper had 2 replacement sets under warranty, both these warped too! since bought aftermarket. If this happened to a car, would be a different story...
To be honest, the noise when moving the bike around, didn't really bother me. When the bike started surging at slow speed (when on the brakes), I got a little more perturbed. That then progressed to more lever travel as the warping got worse, thats when it started to feel unsafe. Anyway, its the multis and diavels that are using the shitty discs apparently.
Mine is terrible, like a screach, bike is in Thursday so may mention it. My 13MY did it but no where near as bad
Mine aren't warped, they have grabby patches on them. When my local bike shop stuck my bike on their mot brake rollers (out of curiosity) they told me the brake variation would fail an mot... I was told that whilst they are brembo discs, they are made to the bike manufactures price / spec. This is not the same as the brembo series oro that you buy as after market ones. I hope they will replace them under warranty, but we shall see.
Mine too, when wheeling around every full rotation of the front wheel I get a lightsaber like squeal out of the discs, not expected from a bike of this quality! Worth mentioning to dealer?
Couldn't the "grabby patches" be the early signs of warping Not sure what else it would be unless you can see patches of different consistency on your discs. my dealers 800 mile demo does the same and he thinks its early warping.
Funny I was looking at the discs at the weekend, and wondered why they were 2 pieces welded together? Big Question for me though are they replacing them with the same Discs as the faulty ones they are taking off?
They aren't 2 pieces welded together, the ridge on the outer edge is part of the design. I put a dual caliper on the discs and there is hardly any run out. By applying pressure on the lever and then rotating the wheel on the rollers we found the patch. It looks like all except one patch on the dusc is glazed. My mechanic thinks this might be due to using sintered pads (I'm using standard brembo pads bought from snells), as you get the same with iron discs and sintered pads.
Mine has the same symptoms, only feel it when pushing the bike around but am gonna claim under warranty anyway.
Mine is bad, so I had them check when mine was in on Thurs. One is perfect, one is a little out but nothing like enough. Also pretty much all of them do it, although mine was worse than average. Paul took the pads out, filed down the edges, seems to have quietened it a bit.
One thing you can try is scrub each disc with scotchbrite pad or maybe steel wool and then clean thoroughly. Sometimes pad material builds up unevenly on the discs.
My '10 1200s failed its MoT on Thursday due to brake fluctuations. They stripped and cleaned the brakes & bobbins and it passed on the second try. Now here's the really funny thing: the bike had been fine on the 80 mile run to the test station, but it's been absolutely dreadful ever since.
