Sram direct mount brakes

[Pepsi]

I have bought new Sram rim direct mount brakes for my new Specialized SL6.

After instalation i noticed a strange sound. First i thought it was a headset. Now i have found out that this sound comes from my front brake.
Sound is stronger when i press brakes and move my bike back and forward.

I have reinstall my front brake but this strange sound is still there.

Is this normal or is there some adjustment trick?

I just checked my calipers. I have a similar ”free float movement” at that point of the caliper, but it is quiet.
