I bought these for my 2014 F-150 which had TERRIBLE brakes. They were terrible almost from scratch and the dealer always said everything was fine. The brakes were very harsh and felt like they were "gaining on". Judging by the forums, this problem arose not only with our truck. I thought it was the rotors and they were warped. After reading many reviews I decided to try these brakes. Boy was it worth it! difference between day and night. These brakes work smoothly and stop effectively. Installation was easy, we did the work ourselves. We're new mechanics, but we often do this kind of work on our bikes. We watched a few videos, followed the instructions and carefully followed the break-in procedure. The kit contains all the parts needed to overhaul calipers and replace pads/discs. It was a huge upgrade for the price. If you like the looks, they also look pretty nice through gaps in the rims.
