Why is my Audi A1 making a noise when I brake and how can I fix it?

I have noticed a strange noise coming from my car whenever I brake, it sounds like a high-pitched squeal. What could be causing this issue and what steps can I take to resolve it?

It is likely that your brake pads have worn out and need to be replaced. This is a common issue with cars and can be easily fixed by taking your car to a certified mechanic. They will replace the worn out pads with new ones, restoring your car's braking efficiency and resolving the noise issue.

Another potential cause for the noise could be a build-up of dust and debris on your brake rotors. This can create a grinding noise when you brake. To fix this, you can try cleaning the rotors yourself or take your car to a car wash for a thorough cleaning of the wheels and brakes.
