My brakes have developed a squeal when applied cold. This started soon after I bought it just over a year ago but repeated visits to the service centre have done little to rectify the problem. The pads were replaced for a different material and the problem went away for a while but has now returned. I have been told that SS brakes need to be stamped on as this is how they are to be used. I brake lightly and in advance which is contrary to what the service centre told me but has not been a problem with the countless cars I have owned and driven. It has also been suggested that I should drive along a freeway and stamp hard to "clean off" the top layer of the pads. My theory is that the pre-delivery mileage of 80km had 75km of hooning it around town by the pre-delivery w****rs or salesman. Any thoughts?
