Abstract
Brake member where the occurrence of brake squeal when a fluctuating load is applied onto the brake member is reduced by way of a brake member or arrangement that includes a backing plate carrying a brake lining which exhibits at least one contact surface and side surfaces surrounding that contact surface and in which the side surfaces are connected to the contact surface and to the backing plate. The contact surface is adapted to exhibit an edge area surrounding the contact surface and in which at least a portion of the edge area exhibits a local deformation stiffness in a direction vertical to a plane through the contact surface which differs, at most, fifteen percent from the deformation stiffness in a central area in the interior of the contact surface. Utilization of this brake member is equally applicable in disc- and drum-style brake arrangements that can suffer from the occurrence of brake squeal when applying a fluctuating load onto the brake member.
