Abstract: A vehicle disc brake pad having a backing plate and a friction pad that includes a complex edge profile formed from a plurality of undulations on at least one side edge of the periphery. Each undulation includes a wave crest and a wave trough that extend toward and away from the periphery of the backing plate, respectively. The brake pad may provide improved thermal management and wear resistance, thereby improving the life span of the brake pad, particularly when used with heavier vehicles such as trucks, crossover vehicles, and sports utility vehicles.

Abstract: The subject invention provides a method of designing disc brake pads. The method includes the step of developing a finite element model of a precursor brake pad design using dimensional and material property information of its backing plate and friction pad to perform a normal mode analysis of the precursor brake pad design. The method proceeds with the step of performing the normal mode analysis using the finite element model to determine whether there is an area on the friction surface having an excitation amplitude that is greater than a threshold value of amplitude. If an area having an excitation amplitude greater than the threshold value is determined, the precursor brake pad design is modified to provide a brake pad design having a relieved portion in the area.

Abstract: The subject invention generally relates to a disc brake pad which has reduced brake squeal in response to a braking event by the incorporation of a relieved portion to the center section of a friction pad along an outer edge or inner edge thereof, or along both edges. The invention is a disc brake pad which includes a backing plate and friction pad attached to the backing plate.

Abstract: A brake pad assembly including a molded material affixed to a backing plate which has opposing faces, at least one non-circular opening through its thickness, and tab-like extensions or some other structure for locating and supporting the backing plate in a vehicle brake system. The molded material extends over both opposed faces of the backing plate by extrusion through the openings to provide a unitary structure wherein molded material at one side of the backing plate functions as a friction-generating pad material and the molded material at the opposite side functions as a shim-like noise attenuating element. The number, configuration, and placement of the openings through the thickness of the backing plate is varied to alter the noise attenuating properties of the assembly, further reducing the tendency for modal locking of brake components.

Abstract: A brake pad assembly (10) comprising a molded material (26) affixed to a backing plate (12) having opposed faces (14, 16), one or more non-circular extrusion openings (24, 38) through its thickness, and tab-like extensions (22) or other integral attachment for incorporating the assembly (10) by location and support into a vehicle brake system. The molded material (26) extends over both opposed faces (14, 16) of the backing plate (12) by being extruded through the extrusion openings (24, 38) to provide a unitary structure wherein molded material (26) at one side of the backing plate (12) functions as a friction-generating pad material (28) and the portion of the molded material (26) at the opposite side of the backing plate (12) functions as the assembly shim-like noise attenuating element (32) due to vibration damping properties.
