I have a problem that has stumped several mechanics and friends of mine who are mechanically inclined. Below is a video(sorry for poor quality) demonstrating the issue in question
This disgusting squawking noise comes from the front driver's side only when I am braking. The pads, rotors, and calipers all look fine. I checked out the dust shield, and it wasn't making contact with the rotor(one theory). I checked for any lodged rocks/debris and there are none. I finally decided that maybe replacing the front driver's side rotor would at least make a difference, but no. It is still making the noise. I don't want to keep throwing parts at it until it fixes the problem without knowing what the problem is, as that is pretty costly and I want to know the source of this problem in case it happens again in the future. Thank you all for any advice you can give!
