Rear brakes tend to make an abrasive, almost grinding noise when traveling at low speeds, such as through a parking lot. Most noticeable after a rain, or when backing up and stopping. Inspected by local Meineke and was told everything looks normal and pads were within specs. Attempted to fix problem by replacing pads, did not remedy it. Could possibly be the rotor(s), but it's not significant enough of a problem to get so involved in. Does not seem to be getting any worse, and brakes seem to operate satisfactorily otherwise, just always there. Please be mindful of problem if considering this model used car.
