Auto brake pad manufacturers: Why do brake pads do these tests?
1, why should brake pads do corrosion resistance test?
Because the brake pads of the car are exposed to the air to work, so the wind, rain, snow, fog to work, if the user in a period of time, poor quality brake pads will rust phenomenon, this situation may lead to driving due to the corrosion of metal parts, brake return is not smooth, there will be dragging phenomenon, It is also possible that the corrosion of the lining will cause poor braking effect and bring potential safety accidents.
2, why should brake pads do water resistance test?
As the car brake pads are exposed to the air in the parts, the general host supporting manufacturers of products will require water resistance test, water resistance test types are: spray test, sprinkling test, water test and immersion test, mainly to detect the brake pads in rainy days, water road conditions and other conditions of the product braking effect.
3, why should brake pads do chemical resistance test?
Brake pad friction material is composed of a variety of organic materials and inorganic materials, in the production process, only a small number of materials, such as adhesives in the process of heating changes, and many materials are not changed, that is to say, the chemical properties of these materials after the completion of manufacturing, still preserve the original characteristics, Therefore, some performance changes will occur under the erosion of some organic chemical solvents, which is not allowed.
4, why do brake pads do salt spray test?
Brake pads to do salt spray test, in essence, is to check the corrosion resistance of the product, both to check the corrosion resistance of friction materials and at the same time to check the corrosion resistance of the coating, to do salt spray test.
