The brake fluid how to choose and buy? What is a good brake fluid

by:DEFUS     2020-06-16
There are three types of brake fluid. When the choose and buy should choose reliable manufacturers, and the level is higher, the better. 。 The brake pressure is commonly 2 mpa high up to 4 ~ 5 mpa. All liquids are incompressible features, in a sealed container or fluid-filled pipeline, when the liquid pressure, can quickly and evenly each part of the liquid pressure conduction. Below small make up with you about the brake fluid how to choose and buy? What is a good brake fluid? As far as possible buy for auto brake fluid providing long-term fuel injector manufacturer's products, to ensure that the quality is reliable, stable performance; As far as possible to the qualified sales places to buy, in case of false and inferior product; It is best to use professional equipment be replaced, such ability more thoroughly, not residual impurities, at the same time avoid the gas resistance. On the type selection, should consider to choose synthetic brake fluid, don't buy alcohol type brake fluid has been eliminated. Brake fluid with water absorption properties, can appear the boiling point, pollution reduction and oxidation of different level, long time don't change will corrosion braking system, bring hidden danger to traffic. Recommended, brake fluid is two years or 40000 kilometers must be replaced once a year. 5. The brake fluid level is higher, the better, the brake fluid level is higher, the better security protection. In general, the micro car selection suitable HZY3 standards and perfection of the brake fluid, and high-grade car suggestion choice HZY4 standard of brake fluid. Miniature, choice of low-standard cars HZY4, of course, also don't have any problems, but also better. ( 1] Method first, as the seal in the brake system for rubber wrist, the long-term immersion chemical changes will happen in the brake fluid, cause skin wrist expansion or contraction, so as to affect the braking performance, therefore should choose and rubber compatibility good brake fluid. , which is the second high temperature performance, is the brake fluid under high temperature air resistance of the resistance, with the index of 'balance return point' to examine. The balance of a brake fluid backflow point is higher, its the better the performance of high temperature, at the same time also shows that the higher quality levels. The third is the low temperature performance of the brake fluid, brake fluid [ 1] 40 ℃ low temperature flow property, using the movement of the brake fluid viscosity to examine. If under the temperature of the brake fluid viscosity is too high, will affect the braking force. Fourth, because a lot of parts in the automobile braking system are metal materials, so a good brake fluid should join various anti-corrosion additives, so as to prevent the brake system by corrosion. Buy brake fluid attention points: one is to qualified sales places to buy as far as possible, to prevent counterfeit and shoddy products; Replace the brake fluid, it is best to use professional equipment for replacement. 2 it is to try to buy long-term fuel injector manufacturer for auto brake fluid providing products, to ensure that the quality is reliable, stable performance. At the same time, the third is the type choice, had better choose synthetic brake fluid, don't buy alcohol type brake fluid has been eliminated. What is a good brake fluid 1, boiling point, the higher the better, low evaporation. Not less than 205 ℃, boiling point when the car was going for a long time, or downhill driving at high speed, the temperature will be up to several baidu. As the brake shoe temperature rises, the brake fluid temperature rise, if the brake fluid boiling point is not high, the brake fluid vaporizing, bubbles, brakes is waxed feeble, and don't achieve brake immediately, cannot guarantee the security of driving. 2, good for various metal rustproof brake system. Brake fluid corrosion resistance is stronger, but high quality brake fluid for all kinds of metal corrosion greatly reduce anti-rust, can prolong the life of the brake pump, if add the inferior brake fluid will soon a corrosive action on metals, cause a harm to driving. 3, low temperature fluidity is very good, it in cold region is especially obvious. Using high quality brake fluid in cold as sensitive and reliable braking. Use inferior brake fluid temperature and poor performance, high freezing point, below - 20 ℃ temperatures will have solidified phenomenon, significantly affect the safety of driving. 4, for a variety of rubber is not corrosion. High quality brake fluid after using rare cup expansion deformation phenomenon seriously. If use inferior brake fluid, cup expansion deformation, easily lead to vehicle oil, brake, cause an accident. Standard brake fluid expansion rate is at zero. 1% - Within 5%. 5, use for a long time without sediment. The brake fluid under high temperature condition to use for a long time, quality is not stable can produce thermal decomposition, sediment, also affect the braking performance. More about 'how the brake fluid of choose and buy? What is a good brake fluid 'small make up is introduced here, hope useful for everyone. More auto parts information, please attention.
