I've had those pads on there for a few months now! (Maybe you will see that I'm not THAT hard of a driver... but I try and avoid hard braking, timing stop lights, releasing gas pedal early and coasting to light, etc.) I think they've been on there for about 8 thousand miles now.
But back to the squeak, where should I look!? I can still hear it and it's SO annoying!
