  • Patent number: 6481544
    Abstract: A disk brake and brake pad set that includes a brake disk (2) and two brake pads (4, 6) wherein each brake pad (4, 6) has a carrier plate (8) and a friction lining layer (10, 12) arranged on the carrier plate (8). Each friction lining layer (10, 12) has a central area (22) of identical layer thickness,an area (14, 16; 18, 20) of reduced layer thickness at at least one end of the brake pad (4, 6),and a separating line (24) that defines an edge between the central area (22) and the at least one area (14, 16; 18, 20) of reduced layer thickness. When the two brake pads (4, 6) are arranged opposite each other on either side of the brake disk (2) the areas (14, 16; 18, 20) of reduced layer thickness of the friction lining layers (10, 12) are tangential to the brake disk (2) and the areas (14, 16; 18, 20) of reduced layer thickness of the friction lining layers (10, 12) and the separating lines (24) are arranged asymmetrically relative to each other.

  • Publication number: 20020000349
    Abstract: In the case of a disk brake with two brake pads (4, 6) arranged opposite each other on either side of s brake disk (2) where the brake pads (4, 6) is capable of being pressed against the brake disk (2) for braking purposes, wherein the brake pads (4, 6) comprise a carrier plate (8) and a friction lining layer (10, 12) arranged thereupon and wherein the friction lining layers (10, 12) comprise areas (14, 16, 18, 20) of reduced thickness, it is provided for the brake pads (4, 6) located on either side of the brake disk (2) not being arranged mirror-symmetrically in relation to the areas (14, 16, 18, 20) of reduced layer thickness of the friction lining layers (10, 12) arranged opposite each other.
