How to fix squeaky brakes?

My car's brakes have been making a squeaky noise whenever I press them. It's been going on for a few weeks now. What could be causing this and how do I fix it?

The squeaky noise could be caused by worn brake pads. You should have them checked and replaced if necessary.

Another possible cause could be dirty brake pads or rotors. Have a mechanic clean them and see if that solves the problem.

Sometimes the brake pads just need to be repositioned. This is a quick and simple fix that you can do yourself.
