i have a 2000 hyundai elantra and it seems like ever since i had new brakes put on a few months ago there is a chirping noise whenever i apply the brakes. it doesn't happen every time i apply them but it does it frequently. it seems like it is coming from the front passenger side. what would be causing the chirping noise?

 

Are you sure you did it right? Did you put some silicone behind the pads to eliminate noise? Maybe you put them in wrong, and the wear indicator tabs are rubbing on the rotors?
