I had some front brake work done a few weeks ago - calipers, pads, brake lines. Since then I have a new sound - it sound like loud road noise - like when you drive on groved pavement. This occurs then I'm driving straight and gets louder as I turn to the left, if I turn to the right - like on a right curve, the noise goes away. I tried just coasting to see if it was the brakes sticking but no difference in decel if I'm on a right or left curve. But it's very loud on a sharp left curve - sounds like a semi is beside me. I checked to make sure the wheels are not rubbing - but no evidence of that, the steering is fine, no PS noise if I turn all the way right or left. I'm starting to think it's the tires but I've had these on for 40K with regular rotations and so on. Any thoughts?
