Hi, Bought my Galaxy with 14,670 Miles on the clock, 1 only lady owner before. But on taking the Galaxy in for her 20,000 Mile service I am informed and shown that the Front Brake Discs are worn! The garage owner tells me they find this alot with new cars today, it's because the Disc Pads are too hard and wear the Discs out in no time at all. Anyone else had the same problem or has this never been a problem?
