What are some common issues with the brake system in an Audi 80?

I have recently noticed some strange noises coming from my Audi 80's brakes. What are some potential problems that could be causing this issue?

One possible issue could be worn brake pads. It is important to regularly check and replace them when necessary to avoid potential safety hazards.

Another common problem could be a leak in the brake fluid. Make sure to check the fluid levels and get any leaks fixed as soon as possible to maintain proper braking performance.

In some cases, strange noises when applying the brakes could be due to a faulty brake rotor or caliper. These components can wear out over time and may need to be replaced.
