Has anyone else had the problem of brake squeal when you are not actually applying the brakes? If I am going in a strait line, or turning left, my brakes squeal. If I am braking, or turning right, they do not squeal. This happens when I have been driving for about 20mins. Once it starts it wont stop fot the whole journey. It is a very loud noise, louder that just new pads bearing in. Tried cleaning the brake mechanisms (well I didn't personally, I left it to my father in law :P ), which solved it for about 2 months. But now the squeal is back. The local garage could not find anything wrong. Has anyone got a fairly permanent solution?
