【Car owner's car knowledge]Recently, the Guangdong Provincial Quality Supervision Department conducted a random inspection on the quality of automobile brake fluids and found that nearly 80% of the brake fluids on the market were unqualified. Brake fluid, also known as automobile brake fluid, is a fluid used to transmit pressure in automobile hydraulic brake systems. The use of inferior brake fluid will damage the brake cylinder and cause the brakes to fail, resulting in hidden dangers of accidents. Today, I will introduce some precautions for replacing and purchasing brake fluid to car owners.
Best to replace every two years
When it comes to the maintenance of the brake system, brake fluid is often overlooked by many people. In fact, brake oil is an important transmission medium in the vehicle braking system. After the brake oil is used for a long time, the leather and piston in the brake pump will be worn, so it must be replaced after a period of use.
So, under what circumstances do you need to replace the brake oil? According to professionals, if the vehicle is in normal driving, the brakes are always neglected and heavy, it is necessary to replace the brake oil in time, and use alcohol before replacement. Clean the brake system. When the seasons change, especially in winter, if you find that the braking effect of your car decreases, it may be that the level of the brake fluid is not suitable for the winter climate. At this time, you should also consider replacing the new brake fluid, and choose the viscosity at low temperature. small oil.
Professionals suggest that in general, it is best to check

Professionals suggest that in general, it is best to check the brake oil every 10,000 to 20,000 kilometers, and replace the brake oil every two years or 30,000 to 40,000 kilometers.
Do not use colorless transparent brake fluid
If the quality of the brake fluid is not good enough, it can damage the braking system, reduce the braking performance, and then cause brake lag or even brake failure, resulting in traffic accidents. According to the relevant staff of the Provincial Quality Supervision Bureau, the harm of inferior brake oil is generally not easy to find in a short period of time, and it is very concealed and harmful. It is often difficult for inexperienced car owners to identify the authenticity of brake fluid with the naked eye, but it can still be distinguished by color and smell.
According to professionals, inferior brake fluids often have an alcohol smell, the liquid is like water, and magazines and suspended matter may appear, while qualified brake fluids are similar in shape to honey, pale yellow or dark yellow, and the friction will increase after dripping in the palm of the hand. getting hotter.
It is suggested that car owners should not be greedy when choosing brake fluids, it is best to buy brake fluids with the label DOT4 or higher. In addition, for brake fluids that are too thin or completely colorless and transparent, car owners are advised not to take risks.
Do not mix different brands of brake fluid
In addition, it should be reminded that in the process of using the brake oil, gasoline, diesel oil, engine oil or glass water cannot be mixed into the brake oil, otherwise the braking effect will be greatly affected.
In addition, different types and brands of brake fluid should not be mixed. For brake systems with special requirements, a specific brand of brake fluid should be added. Due to the different formulations of different brands and types of brake fluids, mixing brake fluids will cause the brake fluidity index to drop. Even those brands that are compatible with each other and indicate that they can be mixed or replaced, do not mix them for a long time.
