My 08 (build 11/07) has no brake squeal or noise at all, however it does have trigger happy brakes. I've had to learn to brake all over, but driving TJ's for ten years will condition you to not having brakes. On my TJ's you could place your foot completely on the brake pedal with no effect at all. It took considerable pressure to actually get braking. No so with the FJ... hit the pedal like that and you'll throw stuff all over the vehicle.. Massive brakes.. Ron
You don't happen to know which range of models was affected, do you?
I see you've got an '07, but I don't experience any squealing or misbehaving brakes on my '08...
