  • Patent number: 8225911
    Abstract: A brake pad assembly is provided that includes a backing plate including a first surface, a second surface opposite to the first surface, and at least one opening. Also included are a friction material associated with the backing plate and a shim plate having a first shim surface and a second shim surface, and a tab projecting from the second shim surface. The shim plate is securely fastened to the backing plate by inserting the tab into the opening such that the friction material, when plastic, embeds the tab inside the opening by flowing through the opening, and subsequently hardens around the tab.
