How can one stop brakes from screeching? I'm hearing that annoying sound when you use your brakes and you get the chills from the screeching sound.

I have disk brakes and a relatively new bike.

It happens to be front tire shown below.  I checked for contaminant and none exists.
I would recommend swizzstop discbrake silencer, and sand the surface if the brake pads with fine sandpaper.
