Automotive brake Pad (semi-metal, less metal, NAO)

Automotive brake Pad (semi-metal, less metal, NAO)

Automotive brake Pad can be divided - for the brake disc brake - drum brake for the brake hoof - for large trucks to make the film

Technical points from the formula are: semi-metal, less metal, NAO
Brake drum brake to fit the hoof, but most people called on the Commission refers to brake pads and brake hoof, so the "brake disc" to be specified to fit the disc brake pads. Is not the brakes.
Automotive brake lining is fixed in rotation with the wheel brake drum or disc brake friction material, in which the friction linings and friction lining block to withstand external pressure, the role of friction so as to achieve the purpose of vehicle deceleration.
By braking mode can be divided into different brake: drum brake and disc brake pads brake two, according to the different brake materials in general can be divided into the type of asbestos, semi-metal type, NAO-type (that is, without asbestos organic type), three brake.
Drum brake and disc brake pads are brake block friction, the friction block is promoting the extrusion piston brake caliper brake disc in the friction materials, as a result of friction, friction will gradually wear block, general lower cost in terms of brake wear faster. Friction block friction materials and floor is divided into two parts, the wear of friction materials can be used after, after the use of friction material, brake disc and the floor will be in direct contact, and eventually the loss of braking effect and brake disc damage , while the cost of repairing the brake disc is very expensive, in general, the basic requirements for brake wear mainly friction coefficient, excellent thermal insulation properties.
Therefore, instead of the brake drum brake drums, disc brake rotors are not. Drum brakes with disc brakes is to distinguish according to the shape, the drum brakes for the curved surface friction, the friction disc brake for the flat surface.
