Did ya make sure your caliper pins are nice and free, if they do not move easy that can cause quik warpage and uneven ware. When i got my frozen rotors the fellas pushed the issue that the pins need to be free. i had to just get new brakets because i got tired of tryin to get them free with heat and so forth. Never seize does not work for caliper pins it gaulds very fast, regular brake caliper lube is best. If ya get hawk pads with the frozen rotors they give ya a pack of good high proformance lube, make sure to use it. Best of luck
