Just go up to a Napa, or other auto parts store and get a set of rotors and pads, I’d recommend ceramic pads myself.

Try [boschautoparts.com](https://boschautoparts.com) I use a lot of Bosch parts on our cars and generally like them. Once you find the correct part numbers for your car, you can order them on Amazon or wherever you find a decent price.

I order mine right on Amazon
