    once again, thanks for the tip... BUT..

    I've tried all methods of cleaning the discs, to no avail....
    Simply, they're buggered....

    got to approx 6.5K miles before they warped and reckon lots of track days and the trip to Spain with DP racing pads in didn't help...

    not a massive expense really I suppose in the grand scheme of things... At least my insurance is dirt cheap.....!!!

    Whoops... sorry... different thread.....

    Okay Reggie.
    You may like to know Trade Direct (08705 134859)do a pair of replacement rotors and buttons to fit the original centres, and you can tweak the spring washers as you build them up to give loads of float. A pair for my exup 18 months ago was 120. One word of caution - their rotors don't work very well with EBC HH pads. Or motomecca is usually a cheap source of Brembo parts, and RSVR.net sells the original discs as well as the Brembo full floating race jobbies.

    the spieglers were $356, I just looked at the receipt. No tweaking of the rotor springs or anything, they're real ff buttons. And they jangle over potholes when not on the brakes, but other than that, no increased noise. FYI

    -if you do decide to go with them shoot me a pm so I can give you a few heads-ups regarding the install

    Rotors still pulsating

    Back to this issue again, I have used the above mentioned technique to free up the buttons of my Tuono, I have also freed up the cylinders in the calipers by cleaning them extensively by WD40, I also rubbed the stock Brembo pads with steel wool to be sure that they are not glazed but all these with no success. The rotors are still vibrating at above about 80km/h and I don't know what else to do before I go to my local dealer and see if can get new rotors under warranty (no big chances I think).
    Maybe changing the pads with softer organic ones (like Ferodo Platinum) or rubbing also the disk surfaces with steel wool to clear it from pads residue?
    I wonder if we are ever going to find a permanent solution to this very common problem or if Aprilia can officially explain this systematic behaviour (Clarkie maybe?)
    Reggie what did you do after all?

    Sometimes the discs are warped and need to be replaced. If you replace them I would go with after market discs and that will end your problem.

    I just did this mod this evening and will try them out tomorrow. I hope it's the fix, which it sounds like it will be. Thanks for this info.....

    I did this and over time it became very loose and noise. I had to bent the spring partially back. there's still plenty of movement.

    I did the same but I used anti sieze compound. It's quite a bit stickier and didn't run out when heated up. Seems to have worked well. Another thing to remember is that if your caliper pistons aren't moving together, IE, inner and outer pistons pressing the pads against the rotors you'll get a pulsation at the lever also. Just another thing to check before buying a new set of rotors. Also, a buddy of mine once had a tire replaced and the shop bent his rotor carriers during the tire change. They then tried to deny that it was them and even tried to blame him using a disc lock as the cause. The resulting bent carrier felt like a warped rotor at the lever.

    I used to swear by DP pads. I used them exclusively until I realized that the compound is so abrasive that my discs were completely shot when it came time to replace the pads yet again. I don't know how many pads I'd been through by that time though. All I'm saying is that I don't think it's a good idea to run that abrasive a pad on the stock rotors. I've just changed mine out for Carbonne Lorraine SBK5 pads as the consensus seems to be that they're quite gentle on rotors.......I'll find out once I get the bike back together.....sean

I always get the feeling that to ride a Tuono you have to be a real man, prepared to fight it every step of the way, where as on the Triumph you can have an off day and not be left feeling inadequate"

    I just did this to my brakes. I had been getting a slight pulse when coming to a slow stop. Nothing in the higher MPH after I cleaned the buttons. I also de-glazed the rotors at the same time since I had them off. Boy am I glad I did. I never though I was lacking bite and power to stop, but now that I have done this, looking back it is crazy what I was missing. The wobble or pulse from the brakes has also gone away from the button trick, although a side affect is the noise that the rotors make over bumps. I would rather have a little noise here and there than pulsing, weak brakes. Everyone who is thinking about trying it, should do this FREE mod .
