Hello Gents, I would firstly like to let all that read this know that for the past 90 mins i have been scouring the search section to try and get some opinions. But cant get the answer Im looking for. My issue: -1299 pani S-. My Brake pads needed changing so I went with a set of original OEM ones from Ducati. Previous ones were OEM Brembos but not from Ducati. Upon changing the pads now; I have massive brake judder from the front end.. To the point where I could hear the fairings rattling. The harder I brake from higher speeds the more the judder amplifies. Checked the pad seating, calipers, bobins, bearings all to no avail. One of my discs has warped (17,000 miles on the clocks) Discs had loads of life left in them which is a shame. We could debate all day what the reason is for the warped disc, and i have a hunch. But the point is i need a new disc. Or new set of discs. My question to you gents is; Im not sure if I want to buy OEM from Ducati. So i started looking at full floating discs as oppose to semi-float that OEM has. I have heard that Galfer are apparently good, but have never used. And have seen other guys on here use Brembo full float. I think they are the HPKs right? Usage: I fast road my bike 90% of the time on closed mountain roads. Canyon carving, Isle of man, pike peak etc... Very rarely trundle through villages, and then its back up to speed. I have always been happy with the stock braking system. Happy with stock pads. But now that Im in a position that I have to change discs. May I have some feedback about full floating discs on the street? I read that they are noisy. Anything other negatives? Which ones would you guys use and why? Any feedback is welcome. I have never used full floating discs and Im thinking to stick to OEM pads if compatible. Thanks in advance for taking the time to give your opinions. Its really appreciated.
Hi Peter, yes calipers checked, cleaned and in good working order. Are the Brembo Serie ORO better for road use than the Supersport Gold ones? Do you have any experience with these? Or the difference is minimal?
I've had galfer in the past very good discs, but I'm currently waiting for some hpk brembos for my 996.
Bought standard discs again. would love to try HPK ot Brembo T Drives though but they are expensive. I Solved the problem, sold the bike!1
Have you cleaned the bobbins that hold the disc to the rotor? You should be able to move them with your fingers.
Dial Guage to see how far out the discs are is happening tomorrow. Bobbins, pads and calipers was the 1st thing I checked. I have seen other members complain about easily warped discs on the Pani. So Im hesitant to buy stock discs again. I think whether I get Galfers, Brembo Supersport or Series ORO it will all generally have the same result. Unless someone else has had a different experience?
Any time I've had judder , it's always been the same root cause .... .... seized bobbins . WD40 or similar on each bobbin , leave a good while , then go around the disk , whacking it with a hammer ( rubber , plastic or hide ) . I mean hitting the edge of the disk , towards the axle , NOT hitting the sides. A bit of sideways wrestling and twisting with your hands won't hurt anything though . Then a good wash down afterwards , with strong soapy water , and/or alcohol . All of this with the wheel removed , of course And I've checked them with a dial gauge , before and after to confirm . It takes a hell of a lot of heat to warp a disk , but I was once chatting to a bloke in a ferry queue who asked my opinion about judder , and one of his disks was blue ! Destined for the bin ..... no doubt about it .
Thanks oldtech, is it possible that i may have a set of faulty pads that send vibrations up? Or is this impossible? Today i put back on the bike the used pads that were on previously. The bike still judders but no where near as badly. Around 70% less i would say if i can quantify it. At first i assumed that because the pads are worn they dont bite as hard down on the disc as the new ones do and therefore the judders is less. But obviously im not a mechanic to know for sure this is all layman's knowledge. Anyone with more experience/knowledge feel fee
That's a bit of a head-scratcher . Interesting that fitting previous pads made a noticeable improvement . I reckon that the pads themselves are the least likely cause of the trouble . Makes me wonder if the pistons aren't moving smoothly in the calipers , or if there is a sticky spot in the bore ? I'm assuming that you had to push the pistons back to change the pads , and that you are getting good firm pressure at the brake lever .
It baffled me. If the pistons in the caliper are not working in tandem then am i right in assuming that it could cause this type of judder issue? But why would putting the worn out pads back on resolve it considerably? Also, one of the first things i did to diagnose, is take the pads out. Blast the caliper with brake cleaner then use a toothbrush to really get in there and clean it. I made it spotless. Maybe it's a problem with hydraulic pressure? Air bubble or something I was reading about? Makes the pistons not work together?? the Brake lever pressure is good/normal. No issue there.
Unless you did some serious braking consistently from mental speeds, then stopped and held the brake on as hard as you could for a while as they cooled then you will not have warped the disc. To warp the discs on any modenr bike you practically have to do it on purpose. I've had a bit of judder many times after trackdays, it soon clears up by giving the discs a good clean and then some gentle braking over long distances to remove the pad deposits.
Thanks for your input Joe. But the judder im talking about rattles the fairings and makes you think youre going to face plant. Undriveable.
I still don't think it would be the discs warped mate, as said it's that difficult. Could it be an ABS problem? Maybe a dodgy sensor?
