2012 Chevrolet Equinox - Squeels

what is causing the high-pitched squeak I hear while driving? usually after I have taken my foot off the brake pedal; happens intermittently; don’t think it’s the brakes as I had my inspection in April and they passed.

I would have them inspected again. Squealers on your brake pads cause this exact symptom. Also the dust shieds could be rubbing.
