I have ordered a Power Stop K5737 Brake Kit to replace pads and discs on a BMW X3. Everything was easy to install, but the instructions left a lot to be desired. However, it wasn't anything a quick YouTube video couldn't solve. The brake kit was complete, even including front and rear brake sensors and a brake passage. I've cleaned the rotors thoroughly and applied the brake in all the right places and it's absolutely silent when braking. It has a different brake pedal feel than the OEM brakes and is softer, so I bled the brake fluid and made sure there was no air in the lines. Pedal feel hasn't been significantly affected, and the Power Stop brakes are just softer than the OEM brakes. But they last and work perfectly.
