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 Asbestos brake pads have largely been replaced by non-asbestos organic (NAO) materials in first world countries.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.

Light steel structure workshop is a new type of building structure system, which is formed by the main steel framework linking up H section, Z section and U section steel components, roof and walls using a variety of panels and other components such as windows, doors, cranes, etc.
II. Materials:
The main frame (columns and beams)is made of welded H-style steel.
The columns are connected to the foundation by pre-embeddding anchor bolt.
The beams and columns, beams and beams are connected with high intensity bolts.
The wall and roof are made of color steel board or color steel sandwich panels, which are connected with the purlin by self-tapping nails.
Doors and windows can be designed at anywhere which can be made into normal type, sliding type or roll up type with material of PVC, metal, alloy aluminum, sandwich panel and others.
III. Features and services:
1, Attractive design ----beautiful and elegant looks, use the color steel sandwich panel, the material is
Polystyrene foam.
2, Easy to assemble and dismantle -----can be rebuilt for dozens of time with plugs and screw.
3, Firm structure----steel frame structure and sandwich panels
4, Durable----the steel frame parts are all processed with anti-corrosion coating and can be used for as
Long as 30 years.
5, Reduce cost by integrating &manufacturing &service processes.
6, With reliable quality and efficient service Offer one-stop service from developing, design, manufacturing
To installation
7, Sizes and design are according to requirements
