 No. It is a result of the pads vibrating in their calipers. It is a very high
pitched vibration, like a finger on the moist rim of a glass, so  it sounds
like a squeak.

There are special anti-rattle clips/metal gizmos that are to be replaced at
brake pad service intervals, but sometimes are left out, reinstalled (old
ones), or ignored. Replace these clips, and the sound will cease.

Also, there are some aftermarket goops and gizmos that are supposed to help,
but in my opinion, if you are going to rip your brakes apart to install some
goop, you might as well go to the dealer and get the real deal, and instal the
clips.
