Hi there. I'am trying to fing solution about this problem in my Stelvio NTX 8V 2010. My front wheel is jumping when i am braking. There is pulsation of the handle, the brakes seem to brake and release. Someone with similar problem?

As previously mentioned, the bobbins (incorrectly called buttons)that the rotor floats upon, can get dirty, corroded, or just gummed up with dirt and crud and they no longer allow the rotor to move freely like it should.
To clean them, find a piece of wood dowel that preferably is or can be tapered with some sandpaper so that you can press it snugly into the bobbin from one side, and using friction from the wood, turn the bobbin back and forth while spraying some brake cleaner into the space between the bobbins and the rotor. Do this to every bobbin and then test ride it again.!
No effect of fine cleaning of the discs.
When I took off the brakes I notice that the wheel is slightly bent. This probably affects the discs that I will have to replace. Any experience with wheel centering and quality discs?

I had to replace one disk early on in my ownership because of brake pulsing, later investigation (using a surface table and some decent measuring equipment) showed it was the alloy carrier that bolts to the hub and carries the disk that was bent rather than the rotor itself. I have always suspected that it was damaged by someone during a tyre change.
you mean the axis was damaged?PS: were you able to buy just a new Carrier , does it come with the rotor ?
Or was he talking about the *thing* the rotor is/was mounted to /on ?you mean the axis was damaged?
