Abstract
A friction lining of a braking member in which the lining is fixed to a noise-prevention support and is adapted to be applied against a friction track by the effect of force which is applied to the support over a contact area by a force applying member, this support comprising a laminated structure formed by a stack of a number of wholly metallic sheets contiguous with each other over their entire surface and assembled to each other by localized assembly structure such as welding, crimping or riveting. Braking noise due to the tendency of the sheets to separate from each other at the moment of application of the braking force is prevented by forming at least a part of the localized assembly structure over the actual contact area by which the force-applying member acts on the support which thus has an excellent noise-suppression performance due to its laminated structure while at the same time its thickness does not practically vary at all, whether the brake is in the applied or released condition since the assembly structure is located at the point of application of the braking force.
