Update, the noise was gone for a very short period then came back. I took both rear wheels off, cleaned the rotors, greased the pins and reattached everything then went for a drive. Sound gone FANTASTIC! Few days go by now the noise is back. Pin pointed it to the passenger rear brake. The sound is making me think the caliper isn't releasing as it should or the ebrake needs adjustment. If the ebrake is adjusted wrong could it cause this problem? Also is there an easy way to test the caliper for proper movement?
