Does anyone know the runout spec for 1260 front discs I’m hearing a lot of rub and squeal on the pads at low speed which has been there from new, now covered about 1200 miles and not getting any better as advised by dealer I’ve clocked the discs and get around 0.07 & 0.10 mm runout which doesn’t seam excessive. The callipers and pads look very dry, do they assemble dry from new? I video’d the clocking but I can’t upload the files using ‘upload a file’ from the library
Apparently it's because they are large discs. I've had some success at stopping the noise by cleaning the bobbins. Easy job by putting a nut and bolt through the bobbin and then spinning it with a drill whilst spraying a load of brake cleaner at it. You'll be surprised at how much crud comes off the bobbin and then they turn/flex as they should allowing the disc to float properly.
Interesting what VT4F says above, about a potential solution. Since owning Mutli's, the 1260 my third to date, the first being a 2010 model, then a 2014, they all suffered with the annoying rubbing and slight squealing sound made, when rolling the bike. I've sought advice from the dealerships about disc warping and the like, to be told, there isn't any problem to be concerned about, hence I've just got on with it. I might try the VT4F suggestion and see if it makes any difference.
I've had the same with my 1260, don't notice it on the move but wheeling the bike around the disks make a disconcerting rubbing sound. Also mentioned this to the dealer who said it's normal ignore it, so I have...
Yep it's important regardless of bike to keep floating discs floating otherwise they can shimmy and then warp. It just seems to be more pronounced on the multi due to the large discs as can be noticed when removing the caliper which is where a couple of layers of duct tape are your friend. Give the above method a go, nothing to lose and at the very least will allow the discs to float. Let me know if it stops or even reduces the noise.
Cleaning the discs with something like methylated spirits (needs to a fast drying solvent with NO oil residue for obvious reasons - and meths is cheaper than brake cleaner!). That will also help stop the noise but it will come back after a while so keep the discs clean. I only hear it when wheeling the bike around at home and they work really well when riding.
Look for the slightest pitting/corrosion on the discs potentially caused by wet pads sitting on discs in one spot for awhile. Its A PIA. Im on my 3rd pair of discs at 48000.
Good Question - no idea, I asked the dealer the same question and they don't know either! Maybe that part fits on other Ducati Models and has a use on those?
