Stelvio front wheel jumping when i'am braking

I would STOP what you are doing and take the bike to somebody, like a machine shop, that can actually measure the runouts of the wheel, the rotor carrier, and the rotor.

I would also pull the pads and check them for trueness.

Without information, you are just shooting blindly in the dark.

Or was he talking about the *thing* the rotor is/was mounted to /on ?
On cars with separate replaceable rotors they are sometimes referred to as Hats ?

By many mechanics actually damage come from carrier who is bented and that form reflect to the rotor.
Till now most probably rotor is damaged so I will not buy separate rotor and carrier.
 
DeadEye said:
PS: were you able to buy just a new Carrier , does it come with the rotor ?

The rotor is mounted to the carrier by yhe Bobbins and these allow some relative movement, hence the description floating disks.

I bought a new pair of rotor/disk combinations (which as far as I know is all you can easily get) as the disk thickness was low (but not yet at the wear limit). Problem was solved immediately on fitting these and has not returned in 20K+ miles.
 
On another forum (ADVrider) they said its pad residue transferring while holding the brake at a stop with hot rotors. They suggest to remedy it by multiple braking application from freeway speeds to scrub it off and then NOT hold front brake while at a stop.
Haven't tried it yet (dang winter) but my rotors dial out at .002 on the outer edge where pads make no contact but still get the "pulsing" at the very end of slowing down. Quite annoying.

You can also scrub your rotors with a piece of scotchbrite and brake parts cleaner to rinse. A little tricky to get the wheel side with rotor mounted. You could save doing this to at a tire change and remove the rotor when the wheel off the bike.
