<p>A brake pad (10) includes a backing plate (12) of plastic material, a friction lining (14) overmolded on the backing plate (12) and a metal reinforcement plate (16) embedded in the backing plate (12). The backing plate (12) has a solid peripheral structure (18) and an inner structure (20) made as a grid-like reticular structure having a plurality of cavities (22) evenly distributed on its surface and filled at least partially by the material of the friction lining (14). At least part of the cavities (22) are made as through cavities, whereby the friction lining (14) forms columns (24) which extend into the through cavities (22) and improve the adhesion between the friction lining (14) and the backing plate (12). The area of the through cavities (22) amounts at least to 4.5% of the area of the face of the friction lining (14) opposite to the one in contact with the backing plate (12).</p> |
