Funny sound when pulling in front break lever at high speed

[SFmonsterdark]

sounds a bit like a poker card running against a spoke wheel, very quietly, like a household fan.

This sound only is heard going about 60 -70mph

Any ideas on what might be causing this??

It's the noise that semi floating rotors make at speed.

could be the sound of the lever fracturing
