制动液又名刹车油，它应具备的三大特点是：凝固点低，低温流动性良好；沸点

Brake fluid, also known as brake fluid, should have three major characteristics: low freezing point, good low-temperature fluidity; high boiling point, no air resistance at high temperatures; small quality changes, and will not corrode rubber and metal. The pollution sources of brake fluid mainly come from abrasive particles, grease stains and residual metal burrs generated during the running-in period of the automobile; foreign intrusions such as dust, sand, fiber, grease stains, etc.; pollutants generated by long-term normal internal wear, such as pistons and The wear particles on the relative moving surface of the cylinder, the wear particles of the rubber parts of the cup, the brake fluid working under high temperature and high pressure will cause the water, solid impurities and other media inside the system to generate new oxides and sludge; improper operation or poor driving habits Severe wear caused by such things. If the brake fluid is not replaced regularly as required, and the dirty brake fluid is used for an extended period of time, it is easy to cause brake jam or failure, internal corrosion of components, oil leakage, pump cavitation, and increase the braking distance of the vehicle.

制动液又名刹车油，它应具备的三大特点是：凝固点低，低温流动性良好；沸点高，高温状态下不会气阻；品质变化小，不会侵蚀橡胶和金属等。制动液的污染源主要来源于汽车磨合期产生的磨粒、油垢和残留的金属毛刺等；灰尘、沙粒、纤维、油垢等外界侵入的杂质；内部长期正常磨损产生的污染物，如活塞与缸体相对运动表面的磨损颗粒、皮碗橡胶件的磨损颗粒，制动液在高温高压下工作会使系统内部的水分、固体杂质等介质产生新的氧化物和油泥；操作不当或驾驶习惯不良引起的剧烈磨损物等。若未按要求定期更换制动液，超期使用过脏的制动液，易导致制动卡滞或失灵、元件内部腐蚀、漏油、泵气穴、加长行车制动距离等。<br>

Brake fluid, also known as brake oil, has three characteristics: low freezing point and good fluidity at low temperature; High boiling point, no gas resistance at high temperature; The quality change is small, and it will not erode rubber and metal. The pollution sources of brake fluid mainly come from abrasive grains, grease and residual metal burrs produced during the running-in period of automobile. Impurities invaded by the outside world, such as dust, sand grains, fibers, oil dirties, etc.; Contaminants caused by long-term normal internal wear, such as wear particles on the relative moving surface of piston and cylinder body, wear particles of rubber parts of cup, brake fluid working at high temperature and high pressure will make the water, solid impurities and other media in the system produce new oxides and sludge; Severe wear and tear caused by improper operation or bad driving habits. If the brake fluid is not changed regularly as required, and the dirty brake fluid is used too long, it will easily lead to brake sticking or failure, internal corrosion of components, oil leakage, pump cavitation, lengthening the service braking distance, etc.
