【Owner's home car knowledge】Automobile brake fluid, also known as brake fluid, is a liquid used to transmit pressure in the hydraulic braking system of an automobile. Because its quality is directly related to the reliability of the brakes, the purchase of brake fluid is related to the safety of riders and must not be taken lightly.
Compared with most private car owners, brake fluid (brake fluid) is one of the things they least care about and understand. When it comes to engines, fuel consumption, and brands, I believe every car lover can say A few words, but when it comes to brake fluid, there are very few people who really understand it.
The higher the brake fluid level, the better?
The answer is yes.
The reporter searched the "national standard for brake fluid" from the website of the National Standard Industry Association: In January 2004, my country implemented the national mandatory product standard GB12981-2003 "Motor Vehicle Brake Fluid" which is in line with international general standards. .

The reporter searched the "national standard for brake fluid" from the website of the National Standard Industry Association: In January 2004, my country implemented the national mandatory product standard GB12981-2003 "Motor Vehicle Brake Fluid" which is in line with international general standards. . According to GB12981-2003 "Motor Vehicle Brake Fluid", the brake fluid is divided into HZY3, HZY4, and HZY5. Corresponding to international DOT3, DOT4, DOT5 respectively. There are different levels of brake fluid. When consumers choose brake fluid, is the higher the level the better? Experts from Sinopec Great Wall Lubricating Oil Company told reporters that the higher the level of brake fluid, the better the safety guarantee. Under normal circumstances, the brake fluid that meets the HZY3 standard is suitable for miniature, medium and low-end cars, and the brake fluid that meets the HZY4 standard is recommended for medium and high-end cars. Of course, there is nothing wrong with choosing HZY4 for small, medium and low-end cars, and it is even better.
Brake fluid is closely related to life?
The answer is yes.
According to researcher Yan Zili, one of the drafters of the national standard for brake fluid, the quality of brake fluid is directly related to the safety of vehicles. In 2005, nearly 100,000 people died in various traffic accidents in my country, among which vehicle brake failure and brake failure were one of the important factors. Because of this, countries all over the world have always attached great importance to the supervision of brake fluid, and western developed countries have brought it into the category of road safety regulations to control it. In our country, the brake fluid is subject to the national industrial product production license management. A technical expert from the Great Wall Lubricating Oil Company told the reporter that Western countries set very strict DOT standards, which cannot be achieved by simple deployment. Many low-priced and low-quality brake fluids in the domestic market are marked to meet the DOT3 standard, but the product quality is not up to standard.
Brake fluid must be changed every two years?
The answer is also yes.
Wei Junqiang, chief engineer from Beijing Auto Repair Company, said that brake fluid has water absorption characteristics, and if it is not replaced for a long time, it will corrode the brake system and bring hidden dangers to driving. He suggested to car owners that the brake fluid must be replaced every two years or every 40,000 kilometers.
According to Wei Gong, the truly qualified brake fluid has several characteristics: it can ensure the flexible transmission of braking force under high temperature, severe cold, high speed, humid heat and other working conditions; it is not corrosive to the metal and non-metal materials of the brake system; It can effectively lubricate the moving parts of the brake system and prolong the service life of brake cylinders and cups. "If car owners don't know how to choose brake fluid, I suggest that they go to a regular 4S shop for replacement. It is relatively safe there." Wei Gong suggested.
