Brake brake by different ways can be divided into: drum brake pads and disc brakes are two, according to the different materials of the brake pads can be divided into asbestos-type, semi-metallic, NAO-type (that is, Asbestos organic type) brake pads and other three.
With the rapid development of modern science and technology, the brake pads themselves, like the components of other brake systems, have been constantly evolving and changing in recent years.
In the traditional manufacturing process, the friction material used on the brake pads is a mixture of a plurality of binders or additives, and fibers are added thereto to increase the strength thereof to reinforce them. The following is a brief talk about several different types of brake pads.
1, asbestos-type brake pads, the oldest and most widely used asbestos brake pads in the composition ratio, asbestos accounted for 40-60%, but asbestos has been confirmed by the medical profession is a carcinogen, the potential of the human body harm.
2, half-metal hybrid brake pads, semi-metallic brake pads are made of coarse steel wool as an important reinforcement and fiber mixture.
3. Asbestos-free organic brake pads Asbestos-free organic brake pads are an asbestos replacement for brake drums or brake shoes.
