The brake fluid, brake fluid is also called, is an important factor affecting the performance of the vehicle brake system, brake oil in use, the quality factor of concern. So, what is the quality ofbrake fluid, it should have what characteristics?

1, low temperature fluidity is very good, this is particularly evident in cold region. The use of high-quality brake fluid brake in the cold sensitive, reliable. And the use of poor quality of brake fluid temperature performance is poor, the high freezing point, the temperature will be lower than 20 DEG C solidification phenomenon, greatly affecting the traffic safety.

2, the brake system of various kinds of metal corrosion. In general the brake fluid strong corrosion, but the quality of brake fluid is greatly reduced for all kinds of metal anti-corrosion rust proof, can prolong the life of the brake pump, if with a poor brake fluid would quickly corrode metal, cause harm to the road.

3, all kinds of rubber corrosion. Quality of brake fluid after using rare cup severe swelling deformation phenomenon. If the use of poor quality of brake fluid, easy to skin bowl swelling deformation, resulting in leakage, flipping the vehicle brake, causing the accident. Standardbrake fluid expansion rate is generally within 0.1%5%. 5, long-term use without sediment. The brake fluid used for a long time under the condition of high temperature, the quality is not stablecan produce thermal decomposition, sediment, also influence the braking performance.

4 boiling point, the higher the better, lower evaporation. The boiling point of not less than 205 degrees, when the car is running at high speed, long time or when driving downhill, the temperature will be up to several Baidu. The brake fluid temperature increases with the increase of brake shoe temperature, if the brake fluid boiling point is not high enough, the brake fluidevaporation, air bubble, the brakes on weak, not immediately reach the purpose of brake, it can not ensure the running safety.
