Hi,
Does applying the brakes cause the sound or change the sound? Also, if you look at the brake rotors, is there any evidence the pads are worn, and you are touching metal to metal causing the noise? In pic 1 below, I circled the rotor. Check the surface to see if there are grooves or cuts in the steel.
Next, place the vehicle on a slope. Place the vehicle in neutral and release the brake pedal to see if the vehicle moves normally. This will help determine if a brake is hanging up for you.
Also, does the parking brake work properly? There are brake shoes in the top hat of the rotor. Something may have come apart there as well. See pic 2.
Let me know what you find or if you have other questions.
Take care,
Joe
