প্রথমে ব্রেক ডিস্কের কথা বলা যাক।ব্রেক ডিস্কসাধারণত মাঝারি বায়ুচলাচল ডিস্ক, ছিদ্রযুক্ত বায়ুচলাচল ডিস্ক এবং সিরামিক ব্রেক ডিস্কে বিভক্ত। নাম থেকে বোঝা যায়, মাঝারি বায়ুচলাচল ডিস্ক ভিতরে ফাঁপা, এবং ঠান্ডা বাতাস মাঝখান দিয়ে ঠান্ডা হতে পারে। এটি সাধারণত সামনের চাকার জন্য ব্যবহৃত হয়ব্রেক ডিস্ক of civil vehicles. Perforated ventilating plate Perforated ventilating plate is to perforate the surface of the ventilating plate to ensure air circulation to the greatest extent and reduce heat attenuation. The perforated ventilating plate is one level higher than the ventilating plate. Ceramic ব্রেক ডিস্ক are not ordinary ceramics, but reinforced composite ceramics composed of carbon fiber and silicon carbide at a high temperature of 1700 degrees. The weight of the ceramic disc is less than half of the ordinary cast iron disc. For example, the SLR MCIAREB with ceramic brakes has a front wheel brake disc with a diameter of 370mm but a weight of only 6.4 kg. The CL-CLASS, which uses ordinary ব্রেক ডিস্ক, has a front disc diameter of 360mm but weighs up to 15.4 kg. Although the ceramic brake disc has excellent braking performance, its price is very expensive. For example, the optional price on high-performance sports cars of Porsche and Audi is more than 100,000 yuan.

ব্রেক প্যাড again. Generally divided into asbestos type ব্রেক প্যাড, semi-metal type ব্রেক প্যাড, low metal type ব্রেক প্যাড, ceramic type
ব্রেক প্যাড, NAO (non-asbestos organic matter) type ব্রেক প্যাড. The so-called asbestos-type ব্রেক প্যাড are the earliest ব্রেক প্যাড used at low cost and easy to manufacture. Early and common use. However, asbestos materials have been confirmed by the medical community to be carcinogens and their use is now banned. From the appearance of semi-metal ব্রেক প্যাড, it has fine fibers and particles, which can be easily distinguished from asbestos type and NAO type. Compared with traditional brake materials, it mainly uses metal materials to increase the strength of the
ব্রেক প্যাড.At the same time, temperature control and heat dissipation capabilities are also superior to traditional materials. However, because the material of the brake pad contains more metal components, especially in a low temperature environment, excessive braking pressure will cause the surface between the brake disc and the brake drum to wear and produce noise. From the appearance of low-metal ব্রেক প্যাড, low-metal ব্রেক প্যাড are somewhat similar to semi-metal
ব্রেক প্যাড, with fine fibers and particles. The difference is that they have lower metal content than semi-metal ব্রেক প্যাড. Ceramic ব্রেক প্যাড The ব্রেক প্যাড of this formula use new ceramic materials with low density, high temperature resistance and wear resistance. It has the advantages of no noise, no dust, no corrosion to the hub, long service life, and environmental protection, but the price is higher. As for the NAO (non-asbestos organic matter) ব্রেক প্যাড, it should belong to the legendary artifact. It has the advantages of no dust pollution, low wear, low noise, and the service life is significantly extended.
