Not necessarily anything to do with the brakes, can also be a sign of a bad wheel bearing. Can be as simple as a stone trapped in between the brake rotor and splash shield. From the rear it can also be axle noise (from the splines or the CV).
Best thing to do is jack up one corner at a time and spin the wheels by hand to see if you can hear anything. Once you've identified the corner then you can pull the wheel off and inspect more closely.
