hello,



is it true that if you wait that your brake light turns ON to change your brake pads, it's already too late, and then you will also have to change the brake pads sensors that alerts you when your pads are dead ?



Also, I have been told that you do not always need to change your brake discs, you can "fix" them, kind of renovate to bring them back to "new", do you recommend it ?



Thank you so much for your ideas.
