How to properly maintain the brake pads on an Audi A6?

I recently bought an Audi A6 and want to make sure I take proper care of it, especially the brake pads. What should I know about maintaining them and when should I replace them?

It's important to regularly check the thickness of your brake pads and replace them if they are less than 3mm thick. This will ensure optimal braking performance and prevent damage to your vehicle's rotors.

In addition to checking the thickness, also listen for any screeching or grinding noises when braking. This could indicate that your brake pads need to be replaced.
