Asbestos was added as an common ingredient to Brake Pads post-WWI, as car speeds began to increase, because research showed that its properties allowed it to absorb the heat (which can reach 500 °F) while still providing the friction necessary to stop a vehicle. However, as the serious health-related hazards of asbestos eventually started to become apparent, other materials had to be found. Asbestos brake pads have largely been replaced by non-asbestos organic (NAO) materials in first world countries. Today, brake pad materials are classified into one of four principal categories, as follows:
Non-metallic materials - these are made from a combination of various synthetic substances bonded into a composite, principally in the form of cellulose, aramid, PAN, and sintered glass. They are gentle on rotors, but produce a fair amount of dust, thus having a short service life.
Semi-metallic materials - synthetics mixed with varying proportions of flaked metals. These are harder than non-metallic pads, more fade-resistant and longer lasting, but at the cost of increased wear to the rotor/drum which then must be replaced sooner. They also require more actuating force than non-metallic pads in order to generate braking torque.
Fully metallic materials - these pads are used only in racing vehicles, and are composed of sintered steel without any synthetic additives. They are very long-lasting, but require more force to slow a vehicle while wearing off the rotors faster. They also tend to be very loud.
Ceramic materials - Composed of clay and porcelain bonded to copper flakes and filaments, these are a good compromise between the durability of the metal pads, grip and fade resistance of the synthetic variety. Their principal drawback, however, is that unlike the previous three types, despite the presence of the copper (which has a high thermal conductivity), ceramic pads generally do not dissipate heat well, which can eventually cause the pads or other components of the braking system to warp.However, because the ceramic materials causes the braking sound to be elevated beyond that of human hearing, they are exceptionally quiet.

I. Explanation of terms:
China Automotive Network Chemical Liquid Transporter Catalogue China Chemical Industry Liquidation Vehicle Automotive Bulletin of China's Ministry of Industry and Information Technology All advertisements of the 8 categories 113 manufacturers 106 chemical liquid transport vehicle brands 2302 chemical liquid transport vehicles Product information, the latest chemical liquid transport Car announcements, environmental announcements, fuel announcements, exemption announcements, pictures, news, and the most timely chemical liquid transport vehicle quote price information. Chemical liquid trucks are widely used for handling corrosive and dangerous media such as acids, alkalis and salts. Tanks often use carbon steel lining rotomolding or stainless steel cans, aluminum cans and other materials. Second, the composition of the structure: The chemical liquid transport vehicle consists of the chassis of the second type automobile, special tanks for chemical liquid transport vehicles, chemical pumps and other components Third, the special parts description: 1. Tank material can be used: carbon steel lined with rotomolded or stainless steel plate 2, tank shape: oval, square round, round 4, chemical pumps: the use of domestic famous enterprises high-quality chemical liquid special pump 5. Function: It can separate or separate warehouses, and pack different chemicals and liquid foods. 6, the internal set of multiple plastic anti-wave separator. Through the high-pressure air tightness test, the tank body has high strength, stable center of gravity, and safe and stable vehicle transportation. Fourth, safety precautions As you may all know, chemical liquid transport vehicles belong to the category of high-dangerous goods vehicles. Although we can familiarize ourselves with the overview, structure composition, and material requirements of chemical liquid transport vehicles through Baidu Encyclopedia, we rarely know which specific hazards exist. How to prevent driving? Here, Suizhou Walter explained to everyone in detail:[1] In fact, chemical liquid transport vehicles are mainly explosive, flammable, poisonous, corrosive, and radioactive. They pose a potential risk to people's safety. The completion of transportation tasks is a technical and professional job. A slight carelessness in the process can cause serious damage to life, property and the environment. Therefore, safety precautions must be followed by drivers and escorts who must possess the qualifications for the transport of dangerous goods; the safety and safety of the second vehicle should be qualified; the third must pay attention to the details when loading the cargo; the fourth is meticulous driving, and the vehicle should be steadily driven. Diligently check, choose the appropriate driving route, and have the proper driving time. Fifth, pay attention to unloading to prevent pollution. Prepare for emergency response.
