Abstract
A brake pad includes a sole plate with outer and inner faces, and a lining made of friction material fixed to the inner face, the lining being delimited by friction and attachment faces, and inner, outer, rear, and front edges. The lining has a collection groove open on the friction face near the rear edge, the sole plate including a suction hole in fluid communication with the collection groove, this hole being connected to a negative pressure source. The collection groove is extended, at an end, by a duct of which the outer end is open away from the friction face, via an inlet, and of which the inner end is open in the collection groove via an outlet forming a cross-sectional jump with the groove. During operation, a negative pressure exists between the inlet and the collection groove one on each side of the duct.
