Review on 🔥 Enhance Performance with Power Stop K4721 Front Z23 Carbon Fiber Brake Pads and Drilled & Slotted Brake Rotors Kit by Alex Reunion

*****Update***** These brakes have always worked very well but about a year after installation they became very noisy. There was no shaking or juddering, and the rotors weren't warped, but they howled like a banshee when I decelerated off the freeway, such as when exiting the freeway. I've used them for about 3 years and 45,000 miles. About 15% of the pad material was left and wear on the rotors was surprisingly negligible. Since I'll probably be selling this machine soon, I've reverted to one-piece factory rotors and ceramic pads. They also don't stop *at all*, but they're a lot quieter. I have used Power Stop brakes and rotors in several of my and friends' cars and have never been disappointed. I would still consider putting these brakes on another car! (By the way, I'm not getting paid to say this. I'm just a fan.) *****Original review***** Don't trust Revain if the site still says they don't fit in a 2011 Cadillac. Basic model of STS. They fit perfectly! I installed them on my CTS to fix a deformed rotor that the previous owner left me. I followed the recommended break-in procedure and they've been working great ever since. The rotors are strong and will undoubtedly last tens of thousands of miles. They also look very cool! The pads fit perfectly. The supplied hardware is also first class. Overall, this was the easiest and most enjoyable brake job I've ever done, partly because of the Cadillac's ease of maintenance, but mostly because of the high quality of this brake kit.
