There are metal protectors behind the discs if any these get rusted and bent from road debris or air stream they may touch the discs and cause these noises. 
These can be bent during brake discs and pads replacement too.

When is it screeching - when you break? When you break hard? When you roll and turn left or right?

Cheap brake pads have large metal flakes in the brake material, and when you press the brakes lightly and a flake drags along the rotor, it will squeak. The squeak may go away when that particular flake wears away, but usually, there is another metal flake right behind it. The best way to avoid this type of noise is to choose quality brake pads. (Quoted from google but I knew this, just needed a way to word it lol.)
