[Auto Repair Knowledge]How to distinguish the authenticity of brake fluid?

carBrake fluid as car hydraulicsBraking SystemThe working medium must have good high temperature resistance to air resistance. When unqualified brake fluid is used, it is easy to produce air resistance in the brake system, which will cause the brake to lag, and seriously cause damage to the brake system components and cause the brake to fail completely. When car owners choose brake fluid for purchase or maintenance, because there is no basic inspection method, they can only judge the quality of the product from the mark and appearance. Here are a few ways to identify inferior products for your reference. 1. Products with boiling points of 130°C, 190°C, etc. must be unqualified products; products with a boiling point of less than 205°C at equilibrium reflux are all unqualified products, so don't consider buying them at all. 2. The logo should indicate the product's trademark, specifications, the name, address, and telephone number of the manufacturer. "Imported" products without Chinese characters on the label should be used with caution. 3. All products marked as "alcohol brake fluid" are inferior products; all products marked as jgo, jg1 and jg2 that meet the gbl0830?89 standard are unqualified products. All products that only indicate the special brake fluid for a certain vehicle, but do not indicate the specific model level, should be used with caution. The correct way of marking is: jg3 or jg4 brake fluid that meets the gbl0830-98 standard. 4. The appearance of products that meet the requirements of the label should also be observed. National standards stipulate that the appearance of brake fluid products should be clear and transparent, free of suspended matter, dust and sediment. Those that do not meet the requirements are substandard products. 5. Although the national standard does not clearly stipulate the smell of brake fluid products, there are two situations that can be distinguished from the smell of inferior products: one is the product with an alcoholic smell, and its main performance cannot reach the national standard. Unqualified products; Second, products without any odor can not be qualified brake fluid products, because brake fluid is synthesized from chemical raw materials with special odor, so it has a special odor.
