Friction lining for multiple-disk clutches or multiple-disk brakes

Friction lining for one of a multiple-disk clutch or a multiple-disk brake, the friction lining comprising a plurality of first grooves radially extending from a radially inner lining edge to a radially outer lining edge of the friction lining, each of said first grooves being provided with a pronounced orthogonal transition area between the upper edge of the groove and a surface of the friction lining, a plurality of second grooves are provided, each of the second grooves are provided with a non-rectangular transitional area between an upper edge of the groove and the surface of the friction lining, each of the second grooves extend linearly and are unconnected with the first grooves, and at least one groove having an orthogonal transistional area between the grooves and the surface of the friction lining is disposed between two circumferentially adjacent second grooves, said at least one groove is open at least toward the outer lining edge of the friction lining.
