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.

Disc brake pad for a vehicle

Vehicle brake friction pad

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.

Method of making disc brake pads

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.
