Can the break indicator sensors go bad?

What is your question?

I've been hearing a screeching sound from the front end when driving and the mechanic told me it was the rotors. After having the brakes and rotors changed, I still hear the screeching sound when I drive. I did some researched and found out that it could be the break wear indicator sensor. Is it possible that the sensor went bad, and can it be changed?

What makes this problem better or worse?

The faster I drive the louder it is.
