car maintenanceIn the process,brakeSystem inspection is often not negligible, such as changingBrake pads,Brake disc, Brake fluid, etc. Now the quality of brake fluid is getting better and better, and the replacement cycle is getting longer and longer. Most manufacturers stipulate that it should be replaced every 2 years or 40,000 kilometers. During this cycle, the regular inspection of brake fluid must be avoided. Ignore.

Diagnosis and solutions:

The role of brake fluid

Brake fluid is a liquid medium for the brake system to transmit braking force. Its working pressure is generally 2Mpa, and the high can reach 4-5Mpa. The brake fluid is in a sealed environment. When the brake fluid is under pressure, it will quickly and evenly The pressure spreads to allBrake Cylinder, Is the guarantee of braking, which is extremely important.

Classification of brake fluid

Brake fluids can generally be divided into castor oil-alcohol type and synthetic types, and most of them now use synthetic brake fluids. Brake fluids are also graded. The more common ones are DOT3, DOT4, and the more high-end DOT5, DOT5.1. The higher the number, the better the quality, and it can also extend the maintenance cycle.

Brake oil replacement cycle

The brake fluid replacement cycle is two years or 40,000 kilometers, whichever comes first, but for such an important safety configuration, it should not be taken seriously during maintenance, but should be checked at all times.

The nature of brake fluid

Brake fluids are corrosive to a certain degree and have strong water absorption. If there is too much water in the brake fluid, it is easy to generate air resistance in high temperature environments (such as frequently stepping on the brakes), which is what we often call brakes. The air intake of the system will seriously affect the braking effect.

Check the brake fluid

Nowadays, the general repair shop will prepare professional equipment for detecting the moisture content of brake fluid, and it is best to check it every six months. In addition, do not forget to check the oil level of the brake fluid every time you leave the vehicle. Generally, there is no shortage of brake fluid. If there is a defect, it is very likely that the oil is leaking. This is a big problem.

Selection of brake fluid

When selecting brake fluid, it is best to use the model recommended by the original manufacturer. In addition, I need to remind you that the higher the grade of brake fluid, the better, such as DOT5.1 brake fluid. The boiling point of this oil is very high, which means that the pressure is higher at high temperatures. This high pressure It is not applicable to the rubber hoses equipped with the original factory, it is best to choose suitable brake fluid or equip with metal hoses. (over)
