I have just put my mps in for its first mot and after only doing 15,000 miles it failed on poor braking efficiency. The problem I was informed was that the front discs had warped, which I feel certainly should not have happened with such a low mileage. Has any-one else had problems of this kind, and were Mazda sympathetic to the problen or like in my case just said "out of warranty not our problem"?
