Why do Audi 80 brakes squeal?

My Audi 80's brakes make a high-pitched squeaking noise every time I come to a stop. It's really annoying and I'm worried it might be a sign of a bigger problem. Any ideas on what could be causing it and how to fix it?

The most common cause of squeaky brakes is worn brake pads. As the pads wear down, metal from the brake pad backing plate can start rubbing against the rotor, causing the squealing noise. You may need to have your brake pads replaced if they are worn beyond a certain point. In the meantime, try gently spraying the brakes with water to see if that reduces the noise. But ultimately, it's best to take your car to a mechanic for a proper diagnosis and solution.

It's possible that the noise is caused by dirt or debris stuck in the brake pads. This can be resolved by getting the brakes cleaned out by a professional. Another potential solution is to apply anti-squeal brake lubricant to the back of the brake pads, which can reduce the likelihood of the noise occurring.

I had a similar issue with my Audi 80 and it turned out to be a loose brake pad. As the pads wear down, they can become loose and create a squealing noise. I would recommend checking the brake pads and ensuring they are secure. If they are loose, you may need to have them replaced or tightened to eliminate the noise.
