Squeaking brake?

[Rapid Transit]

Yesterday after some agressive driving I noticed some metallic squeaking sound from the front brakes. This does not happen everytime I step on the brake pedal, and only when I lightly apply pressure to the pedal. The sound is akin to when the pad needs changing. But my front brake pads are almost new. It's most likely my fault but I'm not sure what I did wrong. I switched the stock pads for race pads the one time I went to a roadracing event. Afterwards I put the stock pads back. Did I misalign something during re-installation?
Thanks!

I'm sure everything is ok. Mine squeak all the time.

Squeaks seem to be the norm for the stock pads. Mine do it too, along with creating a lot of dust.

It a norm. Comes from the aggressive brake pads (glazing). Nothing to worry about. Also creates more brake dust. Again, a normal result of having these type of brake pads.
