According to media reports on February 13, 2019, the requirement to install an automatic brake system called "AEBS". When the vehicle is running, the camera and the radar are used to analyze the vehicles and obstacles in front, and the brake function will automatically operate when the situation is dangerous. Japan and the European Union will call for more countries to join, and formal rules will be formulated as early as 2019.

According to the UN Economic Commission for Europe, after the launch of AEBS, the number of accidents at low speeds can be reduced by 38%, and more than 1,000 lives can be saved each year in the EU. After the formal implementation of the rules, the EU will have more than 15 million new cars each year, and Japan will have more than 4 million new cars a year.
According to reports, in Japan, more than 70% of new cars have installed automatic braking systems, and research and development has progressed. Toyota is equipped with an automatic braking system for night pedestrians for high-end small recreational vehicles. Subaru also uses the safe driving assistance system "EyeSight" with automatic brakes and other functions. The Japanese government has set a goal of installing 90% of new cars with automatic braking systems by 2020.
The rules were formulated at the “Regulations for the Coordination of Vehicle Regulations (WP29)â€, a subordinate organization of the UN Economic Commission for Europe, led by Japan and the European Union. The background is that in order to prevent accidents and mitigate the hazards of accidents, countries believe that the development of international rules has become a top priority. It has become a serious social problem for older drivers to step on the wrong pedal and cause accidents. In addition, in the context of increasingly fierce competition in the development of new-generation cars, the rules are also in place to ensure complete safety.
In addition to Japan and Europe, South Korea and Russia also participated in the rulemaking. The United States, China, and India did not participate. If the automatic braking system is actually forced to be introduced, in countries such as Japan and Europe, unequipped vehicles may be difficult to sell. Considering the export of vehicles to Japan and Europe, it is expected that automakers in countries that have not joined the rules will also be equipped with automatic braking systems for new vehicles.

1. Preparation: Clean the working surface and seals, and check if the seals are damaged or deformed.
2. Apply lubricant: Apply a layer of lubricant to the seal and sealing groove.
3. Install the seal: Place the seal into the sealing groove, ensuring that the seal is fully embedded in the groove.
4. Install O-ring: Install the O-ring above the seal, ensuring that the O-ring is fully inserted into the groove.
5. Install the piston rod: Insert the piston rod into the seal and O-ring, ensuring that the piston rod fits tightly with the seal and O-ring.
6. Install the sealing sleeve: Place the sealing sleeve on the piston rod to ensure that it fits tightly with the piston rod.
7. Tighten the nut: Use the nut to fix the sealing sleeve on the hydraulic cylinder, ensuring that the sealing sleeve is secure.
8. Check the sealing effect: Operate the hydraulic cylinder and check if there is any leakage in the sealing element. If there is any leakage, reinstall the sealing element.
