What causes the brakes of Audi 80 to squeal and how can it be fixed?

I have noticed that my Audi 80's brakes make a high-pitched squealing noise when I apply them, especially at high speeds. It's quite annoying and I'm worried that it could be a sign of a bigger issue. Is this a common problem for Audi 80s and how can it be resolved?

The most common cause of squealing brakes in Audi 80s is worn brake pads. Overtime, the pads can become thin and cause the metal indicators to come into contact with the rotors, creating a high-pitched noise. To resolve this, you will need to replace the brake pads with new ones.

Another possible cause of squealing brakes in Audi 80s is brake dust buildup. This can happen if the car is not driven frequently or if you tend to brake harshly. The dust can create a layer between the brake pads and rotors, causing them to vibrate and produce a squealing noise. To fix this, you can clean the brake components and pads with a brake cleaner solution.
