Abstract
The brake pad for a disk brake includes a lining and a plate. The lining includes:—a friction face and a fastening face;—a rear edge;—an inner edge and an outer edge; and—a collection groove extending into the inner edge or outer edge. The plate has a hole, the hole being connected to a vacuum source via communication element. The lining has a rear region including the rear edge and the collection groove, and a chamfered portion such that an area of a friction surface of the rear region increases when a thickness of the rear region decreases, the collection groove being located at a distance from a free surface of the chamfered portion and having a cross-section which extends obliquely towards the free surface of the chamfered portion.
