Why is my Audi car making a high pitched squealing noise?

I have noticed that my Audi car has been making a high pitched squealing noise whenever I brake. It seems to be getting worse and I'm concerned about the safety of my vehicle. What could be causing this issue and how can I fix it?

The high pitched squealing noise when braking is most likely due to worn brake pads and/or rotors. It's essential to get these replaced as soon as possible to avoid any potential safety hazards. I recommend consulting with a trusted mechanic or dealership for a proper diagnosis and repair.

It could also be caused by a buildup of debris or rust on the brake pads or rotors. Try cleaning them with a brake cleaner solution first to see if that solves the issue. If not, it's best to have a professional take a look at the car to diagnose and fix the problem.

Another possibility is that the brake calipers are sticking and causing the pads to drag against the rotors, resulting in the high pitched noise. This can be resolved by having the calipers checked and potentially replaced if needed. It's important to address this issue quickly to prevent further damage to the braking system.
