How to seal the brake fluid? Novices don t understand

The most intuitive way to distinguish between good and bad brake fluid is to check its fluidity, good brake fluid will not flow slowly at low temperatures, as for this low temperature is basically minus 10 degrees.

High-quality brake fluid has the following characteristics compared to low-quality oil:

1. Low temperature fluidity is very good, which is especially obvious for severe cold areas. Use high-quality brake fluid to brake just as responsively and reliably in the cold. The use of inferior brake fluid temperature performance is poor, the freezing point is high, and the temperature below 20 will have solidification, which greatly affects driving safety.

2. Good rust resistance to various metals of the brake system. Generally, the corrosive nature of brake fluid is strong, but the anti-corrosion and rust resistance of high-quality brake fluid for all kinds of metals is greatly reduced, which can prolong the life of the brake oil pump.

3. It does not corrode all kinds of rubber. After the use of high-quality brake fluid, it is rare to have a serious expansion and deformation of the leather bowl. If inferior brake fluid is used, the leather bowl is easy to expand and deform, resulting in oil leakage and overturning during braking, resulting in accidents. Standard brake fluid expansion rates are generally within the range.

4. The higher the boiling point, the better, and the lower the evaporation. The boiling point is not lower than 205, and the temperature will be as high as several when the car is driven for a long time, at high speed or downhill. The temperature of the brake fluid rises with the temperature of the brake shoes, if the boiling point of the brake fluid is not high enough, the brake fluid vaporizes, produces bubbles, and the brake becomes soft, and the purpose of braking cannot be achieved immediately, and the safety of driving cannot be guaranteed.

5. No sediment for long-term use. If the brake fluid is used at high temperature for a long time, the unstable quality will produce thermal decomposition and produce sediment, which will also affect the brake performance.

Pay attention to 5 points when using brake fluid.

Brake fluid is a very critical link in the automobile braking system, which is related to the personal safety of the car owner. Although it is difficult for car owners to distinguish the authenticity of brake fluid only by the naked eye, in the use of brake fluid, many 4S shop after-sales service stations and car repair shops in the city reminded yesterday that car owners should pay attention to 5 points when using brake fluid.

First, do not mix different types and brands of brake fluid. Due to the different formulations, mixing brake fluids will cause the brake oil to deteriorate.

Second, when the brake oil absorbs water or has impurities, it should be replaced or filtered in time, otherwise it will cause insufficient braking pressure and affect the braking effect. This is particularly important due to the generally humid weather in southern China.

Third, 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 and should be replaced in time.

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

Fifth, when the vehicle brakes deviates, 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.

Don't care about it, which are ignorant words, brake fluid is synthetic alcohol, only corrosive to paint, does not react to metal rubber, I don't believe you to see which bottle of brake fluid is made of metal, and whether the leather bowl in the brake cylinder is made of rubber;

However, cheap brake fluid will corrode the brake master cylinder and sub cylinder, and the effect is also weakened, so it is not recommended to use cheap one.

Causes and elimination methods of automobile power steering pumps.

Cause of failure: 1. The filter element is blocked, and the oil pipe is blocked due to the lack of corrosion resistance of rubber.

2. There is deflating at the tubing joint, and air enters.

3. The parts of the booster pump are worn, and the gap is too large, resulting in weak oil output.

4. The oil does not meet the regulations or is used for too long, the viscosity is too large, and the sliding resistance of the blade is large.

5. The oil level in the oil storage tank is too low.

Exclusion method: 1. Clean the filter element with alcohol, replace the oil pipe, and add the hydraulic oil to the specified position.

2. Check the fastening connection parts to prevent air from entering.

3. Check and repair the booster pump and replace the parts with serious wear.
