How can I fix the squeaking noise coming from my Vauxhall Insignia's brakes?

I've noticed that every time I apply the brakes, there is a loud squeaking noise. It's been going on for a few weeks now and it's starting to get worse. What could be causing this and what should I do to fix it?

It is likely that your brake pads have worn down and need to be replaced. I would suggest taking your car to a trusted mechanic to have them inspected and possibly replaced.

You may also want to check for any debris or dirt that could be stuck in between the brake pads and the rotor. If you find any, remove it to see if the noise improves.

Alternatively, the sound could be coming from a loose brake dust shield. This can be easily fixed by tightening or replacing the shield.
