Manufacturing of brake pads consists of two stages: making the actual shoes themselves and the manufacture of friction mass. Composition of the friction layer rather complicated, it includes over a dozen different mineral and organic components. Quite high and the requirements that must comply with the friction layer: High wear resistance of the material stable coefficient of friction, resistance to changes in temperature, speed and ability to pressure from the heated surface inhibitory site to absorb heat good damping qualities Ability to operate at high speeds (over 180km / h) and temperature (over 5000 ° C) clutch must be environmentally safe (no harmful metals, asbestos-free technology) to provide comfort when braking (no vibration and whistles) All the firms that are leading manufacturers of brake pads, consisting of a specialized research laboratory, where specialists are constantly working to improve the technology clutches. In order to confirm the high quality of shoes they are subjected to numerous tests, the most critical of which is a test of strength for the friction material, adhering to the base and check on termonagruzhennost. Manufacturers of special vehicle manufacturers to optimize the friction material is for individual car models, account being taken of their gross vehicle weight, speed and other characteristics. All this leads, naturally, to the fabulous cost, that certainly can not affect the value of finished products. It is for this reason, all the brands that are present in the markets can be divided into two categories: relative prices and relative quality. I would like to give a classification on the technology of manufacturing of brake pads. To the pads of the highest category are often referred original parts and those parts that match the quality of detail of the original vendor (in other words, the manufacturer delivers the product of its production to the conveyors leading automobile manufacturers, as well as the aftermarket, which is called «aftermarket», in the end and here and there products are similar in quality). Tendency for a larger share of the market blocks of the highest category were observed only in the city of millionaires, such as Moscow and St. Petersburg. In these cities, due to the fact that income growth has rapidly and steadily growing demand for the products of the highest category is also very large, popular brands such as: Bendix (company Honeywell Friction Materials); Jurid (Allied Signal); Ragid and Textar ( both - TMD Friction); Lucas (Concern TRW); ATE (continental Teves). Brake pads that category in the capital may be about 75% of the market, when in regions this figure will not exceed 25%. Given that purchasing power in regions much smaller producers Branded To meet customer needs with less pay, introducing a system that includes several levels of quality. In this case, the original quality then only a portion of our products, the remaining products are only approaching «aftermarket» with decreasing prices. Products not in original quality supplied to the markets with a certain sign of ECO. For example, Jurid quality "hidden" behind a special symbol of the letters, which stand immediately after the digital cipher. With the release of products that can be attributed to the middle category, the manufacturer may allow the minor its technological and design nuances, but their share should not exceed 15% margin of documentation auto manufacturers. In this case, all the rules of certification, obtaining a permit to operate, and similar laws should be fully respected. However, it is important to consider compliance with ECE R-90, so as to sell stocks that do not meet this standard in our country is prohibited. Marking, which states that compliance must be applied to the packaging and on the back side of the pad. Before the mark of conformity is applied producing countries. For example, it might look like this: E11 - Italy, E3 - Germany, E1 - Great Britain. Those firms that produce shoes category average (Road House (Concern TRW), Ferodo (Concern Federal Mogul), Remsa) aimed at his already gained market segment in which a reasonable price can take the goods of good quality. In the regions, their share is about 35% in the capital - 50%. Recently, however, there is a tendency to "squeezing" shoes in this category, shoes of famous brands. This may explain the psychology of consumers who are primarily focused on the brand manufacturer, in their view, the well-known brand - the products are more reliable. The third category consists of blocks pretty well-known brands, which his class could not make it to secondary level. These products are subsidiaries of manufacturers of famous brands and independent small businesses. Many of them provide the necessary security and passed the appropriate certification of product quality, nevertheless, some indicators are obviously "limp". For example, they can bring the stability of the quality or lack of comfort under braking. Head of the concern of all brake pads is their heat with frequent braking, because the amount of heat that is released when friction is enormous. In any case, testing and research of new types of production of brake pads do not stop for a minute. Soon we'll be witnessing the emergence of new materials that allow you to forget about the periodic replacement of pads and shoes, the braking with shrill or low performance requirements. Innovation must enter the hybrid cars that can convert energy produced under braking into useful electricity.
