Liugong loader is an important equipment in the field of construction machinery, which is widely used in various construction, mines, ports and other places. In the process of daily use, brake fluid is the key fluid of the loader brake system, and its performance and service life directly affect the safety and operation efficiency of the loader. So, how often is it appropriate to change the brake fluid of Liugong loader? Brake oil plays a role in transmitting pressure, lubrication and rust prevention in the brake system of loaders. After long-term use, the brake fluid will gradually deteriorate due to the absorption of moisture, impurities in the air and high-temperature oxidation, resulting in a decrease in brake performance and even potential safety hazards such as brake failure. Therefore, regular change of brake fluid is a necessary measure to ensure the safe operation of the loader. Generally speaking, the replacement cycle of Liugong loader brake fluid is recommended according to the use and manufacturer's recommendation. Usually, it is more appropriate to change the brake fluid every 10,000 to 20,000 kilometers or every year. However, it should be noted that if the loader is used in a harsh environment, such as high temperature, high humidity, dusty and other environments, the replacement cycle should be appropriately shortened. When changing the brake fluid, you should choose the same model and specification as the original car, and follow the correct replacement steps. First, the loader should be parked on flat, hard ground and the engine should be turned off. Then, open the lid of the brake oil can, drain the old brake fluid, and clean the brake oil pot and brake line with cleaning agent. Finally, add new brake fluid to the specified scale and check the brake system for oil leaks. In conclusion, the replacement cycle of Liugong loader brake fluid should be based on the actual situation and follow the correct replacement steps. By changing the brake fluid regularly, the brake performance and safe operation of the loader can be guaranteed, and the work efficiency and economic benefits can be improved.
