I had these brakes on my 2012 Jeep JKU in June 2017, about 16,000 miles. When first installed they were very spongy and needed to warm up before good pad friction developed. They got better over time, but always worse than OEM brakes. Eventually they got significantly worse, so much so that I couldn't develop enough friction to activate the ABS system. At first I thought the master cylinder was leaking, I replaced the MC, bled the system and tried again, minimal change. I replaced the pads with a set of semi-metallic Raybestos and it became like a new jeep, it was possible to stop. The front Power Stop pads had a very uneven surface, like the pad material was peeling off the pad, which had never happened before. The front pads had minimal signs of wear. The rear pads looked better and were badly worn. The rotors look good and I've left them for now. I recommend sticking with a quality aftermarket like Raybestos or Wagner. These expensive braking systems seem more like an advertisement than a true upgrade to the OEM braking system.
