Hi when I get to higher speed I can hear the rotor ringing, it's the bigger rotor on the front. I hold the lever lightly it goes away. I don't think it's slowing me down, is it just normal for some brakes? Rotor slightly out of true? Mine is the Shimano M486.
Is there is something I can do about it, pads look centered on each side
I don't want to mess with the QR if that is the wrong approach/
