I was driving the 9-3 'vert alongside a concrete wall (which reflects sound well) and noticed a light metallic rubbing-type noise coming from one of the passenger side wheels. Based upon past experience with other cars, I thought it was a brake heat shield rubbing the rotor, since it seemed like cyclical, light intensity contact. I pulled over and felt all the brake rotor heat shields with my hand. They were cold to the touch.

So, now I need to ask...what kind of sound do the Saab wheel bearings make when they're dying? Is that common? Any other ideas? Maybe a sticky caliper? (But the brakes didn't feel too warm.)

Thanks,
Dave

could be the pads against the rotors. Like said above.. could be calipers.
Since the noise doesn't vary with load on the wheel, I think it's not a bearing. If it's pads on rotors, what's the remedy? If it's a seizing caliper, I guess lube the guide pins or rebuild.

Possibly new rotors. They could be warped. This is similar to a problem I had on my 9-3. Does your steering wheel shake a little when you brake?
