What is the common issue with the Audi A7 brake system?

I noticed a strange noise coming from my Audi A7's brake system. What could be the cause of this and what can I do to fix it?

The most common issue with the Audi A7 brake system is brake rotor rust and corrosion. This can lead to squeaking or grinding noises while braking. To fix this, you can try cleaning the rotors with a wire brush or replacing them if they are severely rusted.

Another issue that may cause noise in the brake system could be worn out brake pads. Inspect the pads for any signs of wear and replace them if necessary. Also, check for any debris or dirt buildup in the brake system that could be causing the noise.

If the noise persists, it could be an issue with the brake caliper or caliper pins. These components can become stuck or corroded, causing noise and difficulty in braking. It is best to have a professional mechanic inspect and replace these parts if necessary.
