Bought these brakes after putting a little over 50,000 miles on factory brakes. I have a raised Jeep with 35" tires that I sometimes tow a light trailer on. Installation was easy after watching a few videos online - there was no documentation or instructions in the brake kit I received. My only complaint is that the small black rubber boots used to cover the slide pins were not included with the front kit or pads and the included lithium grease was not enough in my opinion to adequately cover the required areas. The burglary phase was relatively simple and easy to follow, again watching videos online (no instructions) but finding a safe place to stop the burglary near my home was a bit difficult. There was a strong odor and squeaks from the brakes during break-in, both of which occurred while watching a video. I've had to brake hard a few times since installation, which I managed very well with these brakes, but I heard a slight screeching a few miles back. That is, as far as I know, under heavy braking, the pad material is erased from the disc. After a few kilometers the noise disappears and the brakes stop making noise. Longevity is yet to be seen. As I said, I've ridden 50,000 miles on factory brakes, about 30,000 of them with upgraded suspension and bigger tires. If I can get 30-40k miles on these brakes I would say they are of great value as the cost of having my brakes repaired at the dealer, my (not new) rotors turned back almost $600 cheated and only bought an OEM part with new rotors and DIY cost about $20-30 more than buying this kit.
