Scrunch noise when braking

[radback]

I've got a little problem (random one, not always)

sometime, at the end of breaking (maybe half second before the car is not moving anymore) I heard a noise like dead pads on discs, except my pads are ok.
Does anyone have an idea?
I think maybe it's my front trailling arms silent bloc wich are tired...
