Why does the Audi 80 experience vibrations when braking at high speeds?

I recently noticed vibrations while braking at high speeds in my Audi 80. It feels like the car is shaking and I'm worried about potential damage. What could be causing this issue?

This issue could be caused by unevenly worn brake rotors, which can cause vibrations when braking. It's important to have these checked and replaced if necessary to ensure safe driving.

Another possible cause could be worn out brake pads. If the pads are too thin, they can cause vibrations while braking at high speeds. Consider getting them replaced as soon as possible.
