More help needed...

Today I trued my wheels and adjusted the brakes. Now when I push the bike backwards, from the rear wheel I get a loud high pitcher squealing sound with each revolution. Any ideas as to the cause? The rotor does not contact the brake pads and the wheel is "true".

Are you sure the disc isn't slightly warped? A well adjusted brake leaves very little margin for error in the disc.
