2006 EX-L w/50K miles has a loud noise from the brakes when moving very slow (idle row) and softly touching brakes on the passenger side only. The noise is quite loud and like a flute mid pitch noise. Normal braking is fine. It only happens when I rolling at very low speeds and softly touch the brakes. I changed the front pads and resufaced the rotors. The rear pads had more meat than my new pads so I decided to only clean the clips and the rear rotors looks normal. Any suggestions? Thanks in advance for your suggestions.
