Inclined hole for air inlet

A brake pad comprising:

• a backing plate with an outer surface, an inner surface and a lateral edge;
• and
• a lining of friction material fixed to the inner surface, wherein the lining is delimited by a friction surface, an attachment surface, and a lateral edge formed of an inner edge, an outer edge, a rear edge, and a front edge, wherein the lining comprises:
• at least one collection groove open to the friction surface and located at least in part near the rear edge, the at least one collection groove comprising a longitudinal axis,
• wherein the backing plate comprises at least one aspiration hole in fluid communication with said at least one collection groove, wherein said at least one aspiration hole is connectable to a vacuum source to create an airflow, wherein the at least one collection groove is extended at at least one of an end thereof by a conduit, the conduit comprising:
• an inlet opened outside said friction;
• an outlet opened in the at least one collection groove, the outlet forming a section break with said at least one groove such that there exists, in operation, a reduced pressure between said inlet of the conduit and said at least one collection groove through said conduit;
• and
• an axis,
• wherein an angle of inclination between the axis of the conduit and the longitudinal axis of the at least one collection groove is nonzero and is such that in operation the airflow near the friction surface of the lining is not perpendicular to the friction surface.
