Abstract
A brake pad (10) having a mechanical joint formed between a friction member (22) and a metal backing plate (12) by a plurality of rivets (30,30' . . . 30.sup.n). Each rivet (30) has a head (36) and an end (37) with the head (36) engaging the friction member (22) and the end (37) engaging the backing plate (12). During assembly of each rivet (30) with the backing plate (22), a force is applied to the head (36) causing the end (37) to flow in a groove (38) in a die (16) and form a flattened surface. The amount of the force applied to head (36) is limited to create a clamping force between the head and backing plate which holds the friction member (22) against the backing plate (12) and yet noise developed through vibration during a brake application is attenuated as the friction member (22) and metal backing plate (12) vibrate at different frequencies.
