while I'm driving in the subdivision, I can hear this metallic sound from the driver side, it isn't too loud, but I can hear it in the subdivisions w/ the window down. The sound is similar to worn brake pads, but I had the front brake pads replaced not too long ago, but its a light metallic sound. What can be the cause for this sound?

 

??????????

 

could be backing plate slightly touhing the rotor, sometimes happens when doing brakes. just pry it away from the rotor a little in a few spots and see if it stops.

 

oh yeah, the anti rattle hardware may not be centered, and will rub the rotors at odd times like while turning but not while going straight.
