Background
The brake pad is a component in a brake system of an automobile and mainly consists of a brake lining (friction material portion) and a steel backing (metal portion). In addition, some brake pads have noise dampers (also referred to as shims) on the steel backing of the brake pad in order to reduce or eliminate noise during braking. The noise damping sheet is a thin metal sheet and is generally fixed to the steel back of the brake pad by means of adhesion. The specific operation method comprises the following steps: firstly, coating adhesive on a gasket and/or a steel back; and then heating and pressurizing the brake pad pasted with the pad by a pad pressing machine to firmly paste the pad on the steel back.
