I really think the brake thing is not related to pads, it did make the noise at first cuz the pads were new, but no it sound as if it were a cable related to brakes... or maybe something binding in the mechanism.... it even does the noise when the vehicle is stopped and I'm just pushing on the pedal.
By the way, there is also a noise coming from what I assume is the suspension but who knows... it's like the chattering noise an old pickup does when going over bumpy streets.....
