What should I pay attention to when using brake fluid?

1. If gasoline, diesel or engine oil is accidentally mixed into the braking system using synthetic brake fluid, the braking effect will also be reduced due to the incompatibility between the oils.

2. If the vehicle travels normally for 40,000 kilometers or the brake fluid is used continuously for more than 2 years, the brake fluid is easy to deteriorate due to long use, so it is necessary to pay attention to timely replacement.

3. Vehicles equipped with brake fluid level alarm devices should observe whether the alarm indicator light is shining at any time, whether the performance of the alarm sensor is good, and when the brake fluid is insufficient, it should be added in time, and the stored brake fluid should be kept between the lowest capacity scale and the highest capacity scale of the calibration.

4. In the normal driving of the vehicle, if the brake is light and heavy, the brake oil should be replaced in time, and the brake system should be cleaned with alcohol before replacement.

5. When the vehicle brakes deviate, the braking system should be comprehensively checked. If it is found that the leather bowl of the sub-pump is too inflated, it means that there may be a problem with the quality of the brake fluid. At this time, you should choose a better quality brake fluid to replace, and replace the leather bowl at the same time.

6. When changing seasons, especially in winter, if you find that the braking effect decreases, it may be that the level of brake fluid is not suitable for the winter climate.

7. Different types and different brands of brake fluid should not be mixed, and specific brands of brake fluid should be added to the brake system with special requirements. Due to the different brands and different types of brake fluid formulations, mixing brake fluids can cause a decrease in brake oil properties. Even those brands that are better miscible and indicate that they can be mixed or substituted are not satisfactory in use, so do not use them for a long time.

8. When water is mixed or inhaled in the brake oil, or the brake fluid is found to have impurities or sediments, it should be replaced or carefully filtered in time, otherwise it will cause insufficient braking pressure, which will affect the braking effect.

In the use of brake fluid, the most critical problem is that it must be maintained regularly, because brake fluid has strong water absorption, if you do not change the brake fluid for a long time, the boiling point of the brake fluid inhaling too much water will be reduced, and it is easier to produce air resistance at high temperatures, which will affect the brake performance. In addition, brake fluid is also very corrosive, so when adding brake fluid, remember that the leaking brake fluid must be cleaned up in time.

Hope mine helps you!

There are three types of brake fluids. When purchasing, you should choose a reliable manufacturer, and the higher the level, the better. Its braking working pressure is generally 2MPa, and the high can reach 4 5MPa.

All liquids are incompressible, and when the liquid is under pressure in a sealed container or in a line filled with liquid, the pressure is transmitted quickly and evenly to all parts of the liquid. Hydraulic brakes work using this principle.

Precautions for the use of brake fluid.

1) Different types of brake fluids should not be mixed to prevent delamination and failure. Even if the same is a synthetic brake fluid of different brands, it may not have the compatibility of the remaining skin (except for some products that have passed the compatibility test).

2) Replace the brake fluid on schedule (according to the requirements of the vehicle instruction manual), and thoroughly clean the brake system when replacing (it is strictly forbidden to use gasoline, kerosene, etc. as cleaning fluid), especially to prevent moisture, mineral oil and mechanical impurities from being mixed; When switching to a different variety of brake fluid, it should be cleaned once with new fluid.

3) Mineral oil brake fluid has a corrosive effect on rubber parts, and when using this type of oil, the brake system must be replaced with mineral oil-resistant rubber products.

4) The brake fluid should be sealed and stored, especially the alcohol ether brake fluid, so as not to reduce the boiling point after absorbing the moisture in the atmosphere; The tools and containers for filling brake fluid must be used exclusively and must not be mixed with other oils.

5) Brake fluid is volatile and flammable, and fire prevention should be noted; Do not store in the open air to avoid early deterioration and failure of brake fluid.

China's current brake fluid standard GB12981-2012 "Motor Vehicle Brake Fluid" is a mandatory standard, with a total of 15 technical index requirements, namely appearance, equilibrium reflux boiling point, wet equilibrium reflux boiling point, kinematic viscosity (100, -40), pH value, liquid stability, corrosivity, low temperature fluidity and appearance, evaporation performance, water capacity, liquid compatibility, oxidation resistance, rubber compatibility, stroke simulation performance and rust resistance.

There are several characteristics of the qualified spring answering fluid:

1.Under the conditions of high temperature, severe cold, high speed, humid heat and other working conditions, it can ensure flexible transmission of braking force;

2.It is not corrosive to metal and non-metallic materials of the brake system;

3.It can effectively lubricate the moving parts of the brake system and prolong the service life of the brake cylinder and leather bowl.

The performance requirements for brake fluid are:

1. Good viscosity and temperature, low freezing point, good fluidity at low temperature;

2. High boiling point, no gas resistance at high temperature;

3. The quality changes little during use, and does not cause corrosion and deterioration of metal parts and rubber parts.

The use of brake fluid should be noted as follows; 1.If you accidentally mix gasoline, diesel or glass water into the brake fluid, it will greatly affect the braking effect and should be replaced in time.

2.If the vehicle has been driving normally for 40,000 kilometers or has been used continuously for more than 2 years, the brake fluid is easy to deteriorate due to the long use time, and it is necessary to pay attention to replacing it in time.

3.Vehicles equipped with brake oil level alarm devices should always observe whether the alarm indicator light is flashing and whether the alarm sensor is performing well. When the brake fluid is insufficient, it should be added in time, and the stored brake fluid should be kept between the minimum and maximum capacity scales of the calibration.

4.When the brakes of the vehicle fail, the brake fluid with better quality index should be selected for replacement, and the cup body should be replaced at the same time.

5.When changing seasons, especially in winter, if you find that the braking effect decreases, it may be that the oil level of the brake fluid is not suitable for the winter climate. At this time, to replace the brake fluid with a new one, you need to choose a low-temperature and low-viscosity brake fluid.

6.When the brake fluid is mixed with water or inhaled, or when impurities or deposits are found in the brake fluid, it should be replaced or carefully filtered in time, otherwise the brake pressure will be insufficient, which will affect the braking effect.

7.Do not mix different types and brands of brake fluid. For braking systems with special requirements, add a specific brand of brake fluid. Due to the different formulations of different brands and different types of brake fluids, the mixed brake fluid will lead to a decrease in the performance index of the brake fluid.

Change your car's brake fluid regularly. After a certain period of use, the performance index will be reduced due to moisture absorption, chemical changes and other reasons.

It mainly depends on the oil quantity, specifications and models, and moisture content.

The precautions for the use of brake fluid are as follows: Do not mix different types and brands of brake fluid. If the vehicle travels normally for 40,000 kilometers or the brake fluid is used continuously for more than 2 years, the brake fluid is easy to deteriorate due to long use, so it is necessary to pay attention to timely replacement.

In the normal driving of the vehicle, if there is a phenomenon such as braking light and heavy or deviation, the brake system should be checked in time, and the brake fluid should be replaced in time if necessary.

To put it simply, when you maintain the vehicle every year, ask the repairman to check it and replace it in time if necessary.
