Brake Line companies must now focus on enhancing their overall capabilities through technological innovation, building advantageous industrial chains, and collaborating with vehicle manufacturers to improve their配套 abilities. China is currently in a period of deepening reform and transformation, with the benefits of reform being further unleashed. The demands of the vast international market and domestic product upgrades will serve as the driving force for product optimization for brake line companies. Currently, Chinese brake line producers face challenges such as insufficient innovation, significant pressure to reduce energy consumption and emissions, immense pressure on brand development, and low levels of internationalization. The development of the automotive service industry is also insufficient and does not meet the requirements of objective development. Therefore, during the development of brake line companies, the ideologies of vehicle producers, suppliers, financial institutions, and others must evolve to form new insights. These insights should deeply recognize the position and role of the brake line industry in the global supply chain, emphasizing interdependence and actively fostering a sense of the big picture and industrial awareness.

The manufacturing materials and heat treatment processes of brake lines greatly influence the load-bearing capacity and dimensions of sprockets. Before the 1950s, sprockets were commonly made of carbon steel, switching to alloy steel in the 1960s, and predominantly using surface-hardened steel in the 1970s. Depending on hardness, sprockets can be categorized into soft and hard tooth surfaces. Soft tooth surface sprockets have lower load-bearing capacity but are easier to manufacture, have better running-in properties, and are often used in machines with non-stringent size and weight limitations, as well as in small-scale consumer applications. Since the smaller sprocket bears a heavier load in matched pairs, the tooth surface hardness of the smaller sprocket is typically higher than that of the larger one to ensure comparable service life. With the domestic sprocket market already highly competitive and the entry of foreign enterprises into mainland China further intensifying competition, in recent years, many domestic companies have focused on expanding internationally while establishing a strong presence in the domestic market.

Brake lines are a testament to technical prowess, yet Chinese brake line companies lack core technology. Post-joining the WTO, China's automotive industry policies regulated the joint venture equity ratios for complete vehicles, but imposed no restrictions on foreign investment in the parts sector, directly leading to a hollowing out of core technology in the Chinese parts industry. Currently, most domestic independent brake line companies are still at the stage of processing according to provided drawings and mapping out samples. Facing the fast-paced high demand for new models, varieties, and technologies from整车 manufacturers, many independent brake line companies are merely struggling to meet their research and development (R&D) tasks, with no time to improve their foundational R&D capabilities and supporting capacities. With the development of China's automotive industry in recent years, China became one of the world's top automotive producers and sellers in 2010. However, the industry widely believes that due to the lack of core technology and independent R&D capabilities, China can only be termed an automotive giant, not a powerhouse. To truly strengthen, one must start with the parts sector.
