Brake squeal is an everyday problem, so it has been widely studied, mostly in vibration parlance studying modes, noise energy and frequencies. We propose to study the phenomenon from its origin — i.e. the contact — in a tribological approach that combines contact geometry, third body aspect and squealing initiation: thus, a temporal analysis was necessary. Experimental and numerical approaches have been used to identify influential parameters and they give similar results: a really strong correlation exists between the disk geometry and the squeal initiation.
