There are several different ways to address squeaking brakes, including the use of anti-squeal compound (rubbery goo) on the pad backing plate or a lubricant, such as Permatex anti-seize, on the touch-points between the backing plate and caliper. The goo serves to damp out high frequency vibrations. And the lubricant makes it so that even if the pad vibrates, the rubbing surfaces are less likely to create noise. However, these address the symptom and not the root cause.
By bedding the brakes properly, you reduce the tendency of the pads to want to vibrate in the first place. That's why I don't use any goo or lubricant on the back of my pads. If one of my cars starts to develop squeaky brakes, I take it out and do an aggressive bedding session. That always works for me. On the other hand, there's nothing wrong with taking a "belt and suspenders" approach and applying goo
and bedding the brakes.
On caveat: certain brake pad compounds tend to be squeaky by their very nature (e.g. Hawk HP Plus) and there's very little you can do to make them quiet, other than switch to a different make and/or model of brake pad.
