reasons of the steel back brake pads with expanded metal mesh

Now a lot of steel back brake manufacturers have introduced a welded steel mesh technology, which was originally introduced from abroad, first appeared in German car. Now a variety of domestic cars, buses of the brake pads are used in the steel net.
         reasons of the steel back brake pads with expanded metal mesh:
         1, increase support force, using principles of mechanics, expanded metal mesh is a frame structure, with stronger support force, the braking force characteristics in line with the weight of the steel back.
         2, increased friction, the structure is clearly increased the coefficient of friction, so no doubt increase in friction.
         3, where enhanced cooling effect of steel net of veins increase the space, reducing the stress points, it will enhance the cooling effect.
