The brake system is related to the safety of the driver, and the inspection and maintenance of it has become a top priority for the owners. Previously, Xiaobian introduced some issues concerning the inspection and replacement of the brake pads. Today It is to talk to everyone about another important component of the brake system - brake fluid. The role of brake oil Brake oil is also the brake fluid of the car. It is an indispensable part of the brake system. It can pass the brake pressure under the foot to the brake cylinder and push the brake disc to squeeze the brake disc to generate the brake force of the car. Therefore, its quality directly determines whether the car's brake system can play a role. Brake oil level At present, the level of brake oil can be divided into DOT3, DOT4, DOT5, DOT5.1. The higher the number, the higher the level and the better the guarantee. Among them, DOT3 is an alcohol ether type brake oil, its dry boiling point is generally above 205 °C, water absorption performance is relatively strong, high temperature resistance is also relatively poor, so it is less used now; alcohol ether borate type DOT4 is most of us now The type of grade used in the family car, it has better control of water absorption compared with DOT3, and also has better performance in high temperature and corrosion resistance, the dry boiling point is generally 230 ° C; DOT5.1 It is based on DOT4 and has been upgraded and improved. The dry boiling point can reach 270 °C and the performance is better. The DOT5 grade is silicone oil type brake oil. It is usually used in racing cars, and the family car market is basically invisible. Brake oil replacement Since one of the main components of brake fluid is ethylene glycol, it likes to absorb and dissolve water, so the brake oil is particularly easy to absorb moisture, and the boiling point of water is relatively low. When a certain amount of water is mixed in the brake fluid. Its boiling point will be greatly reduced, and the high-intensity friction will cause the temperature of the oil to rise rapidly when the brakes are applied, which will lead to a large number of bubbles, which will make the brakes appear weak or even ineffective. Brake performance, so the timely replacement of brake oil has become a non-negligible thing. The brake oil replacement cycle is usually recommended for 2 years or 40,000 kilometers. For the different models, please refer to your own car maintenance manual. If it exceeds the normal use time, even if you feel that the problem is not normal when you brake normally on a normal day, there will be a great safety hazard when there is a need to brake on the brakes or brake on the brakes for a long time. The replacement procedure of brake oil is more complicated. There should be strict replacement details such as “putting old oil-washing pipeline-adding new oil-exhausting airâ€, so the owner must pay attention to choosing a regular professional repair shop or 4S shop to work. When the personnel are changing, the owner can also pay more attention to avoid irregular operations. In addition, it should be noted that different brands, different levels, different types of brake oil must not be mixed.
