Abstract
A friction lining is designed in particular for clutches and plate-type disc brakes and has an annular body of friction material of which one face forms a friction surface. The annular body has holes distributed around its periphery for the passage of rivets. The holes designed to receive the rivets are arranged in the annular body clear of the friction surface and accordingly do not reduce the area of the friction surface.
