And it's not front to back. We've had our car since the beginning of June and have about 2,000 miles on it. Since delivery I've noticed that the wheels on the driver's side of the car accumulate brake dust much more quickly than the wheels on the passenger side. I would expect there to be some difference between front and back wheels, but not side to side. I've always cleaned all the wheels with the same product and the same tools, and applied a synthetic wax to each wheel shortly after delivery. Thanks to our freakishly hot and dry summer, we've yet to drive the car in the rain or even on wet roads, so that wouldn't have anything to do with it, either. I notice nothing else unusual about braking. The car doesn't exhibit any sort of pull to the left or right during braking (heavy or light, it doesn't matter). There are no unusual sounds, and there's no sense that the car is pulling to the left at any time. Has anyone else observed anything like this? I've had new cars in the past and don't ever remember seeing anything like this on any of them.
