It's easy for cars to brake, and the brakes are controlled by a fluid called brake fluid. Yesterday, the inspection team of the Provincial Bureau of Quality Supervision carried out a special sampling inspection on the brake fluids sold in the two auto parts market of Zhejiang Province and Zhejiang Auto Parts Market and Zhejiang Auto Parts City. The result was that all six products tested were unqualified.
The brake oil known as the "safeguard" has become a "street killer."
Boiling point 125°C lower than standard
Yesterday morning, the quality supervision personnel came to Zhejiang Auto Parts City, which is located on the west of Lushan West Road. In the horse auto parts firm, quality supervisors readily took a bottle of brake fluid, poured it into a beaker, and placed the beaker on an electric furnace for heating. In less than 6 minutes, the brake fluid in the beaker begins to boil, and the thermometer in the beaker shows 80°C. Subsequently, quality inspectors discovered the same faults in the brake fluids of the other five brands sampled in this market and Zhejiang Auto Parts Market. The highest boiling point of the product was only 115°C.
According to quality supervision personnel, according to the national mandatory standards, the boiling point of the brake fluid must not be lower than 205°C. At present, the basic raw material of domestic qualified brake oil is polyglycol ether and its boric acid ester, which is characterized by both high temperature resistance and cold resistance.
Methanol plus water equals brake oil?
According to reports, low-quality brake oils are generally made of methanol, which is a blend of industrial alcohol, and some even add water to it. The boiling point of methanol is only 64.9°C. After mixing with water, the boiling oil produced is usually 80°C.
During the interview, the reporter found that the market price of regular brake oil is about 40 yuan per bottle, and the vast majority of poor brake oil is up and down at 10 yuan. Some operators also admit that these brake oils have problems but they have a good market. Some small auto repair shops in Hangzhou like to buy such brake fluids. Some repair shops know that the product is not qualified but will still be used, because it will not only save costs, but will also quickly cause the brake system to age and rust, resulting in more "make money" opportunities.
Be cautious when buying and using in yesterday's operation, the quality supervision department inspected a total of 7 brake oil distribution points, and quickly tested 6 kinds of products on the spot. As a result, it was found that all were suspected of being unqualified. Law enforcement officers sealed a total of 1083 bottles of brake fluid. Samples are taken to the testing agency for final testing.
The quality supervision department reminds car owners that they must be careful when buying and using brake fluids. It is recommended that they be purchased as large as possible at regular sales points. When using, pay attention to different brands, different types of brake oil can not be mixed, it is recommended that 2-4 million kilometers or once a year.
