Ford focus strange noise when I brake?

When I press the brakes there a squeeze noise kind of like a tighten sound. I think I can feel little something in the pedal too. If any one knows thanks Semper Fi.0311

I don't know what a squeeze noise is, but if you feel like your breaks are tightening or you feel something when you're pushing on them and it makes a squeaking noise, you need new break pads.
