try this... get a tuning fork... or somthing similar
give it a "ding"
attach some added weight to it...
give it another ding...
you get 2 different sounds... (it resonates at a different frequency)
it is overlapping sound waves... like if you are in a tub of water and you move back and forth with the waves (at the same speed as the waves).... the waves compond on each other and get bigger.... this is called resonance
every piece of material has a frequency that causes the sound waves to compond on each other.... this is why a crystal wine glass can shatter when an opera singer hits the same note (frequency) in which the crystal resonates ...
Therefore, if the brake rotor causes the brake caliber to vibrate at its resonant frequency... (by friction) .... it will resonate (squeal)... even though it is not moving.
add weight... different resonant frequency... no compounding of the sound waves
