If you can get the brake pads off yourself, a little trick is to use a pencil and rub the sides and contact parts with the pencil. The graphite in the lead usually stops the squeak. Wheels come under a lot of latteral strain when cornering, and hubs can move (slight bearing wear etc) or maybe slightly distort. Not much, but enough to cause interference.
However, the anti-squeal shims seem a likley place to start. Try the pencil grahite trick on them first.
