   平板车提醒：制动液的选购事关车主生命安全，绝不可马马虎虎，制动液的优劣直接关系刹车的可靠程度。
   良好的粘温性能和低温性能制动过程中，由于摩擦发热可使蹄片温度高达250°C。其热量有一部分传给制动液，使其工作温度达70～90°C，在下长坡等路况行驶需频繁制动时，其工作温度可达成110°C，而在冬季某些地区的制动液温度又可低至-40°C以下，因此要求制动液有良好的粘温性能和低温流动性能。适宜的高温粘度、较低的凝点和低温粘度。
   良好的与橡胶的适应性在制动系统中有许多橡胶密封件与皮碗等，用以保持制动系统完全密闭，因此制动液应具有良好的与橡胶密封的适应性，防止橡胶密封件与皮碗因液油而膨胀、机械强度降低。
   制动液其质量优劣直接关系到平板车行驶的安全性。2005年我国有近10万人不幸丧生于各类交通事故，其中车辆制动不灵、刹车失效是其重要因素之一。正因为如此，世界各国历来十分重视对制动液的监管，西方发达国家更是将其纳入道路安全法规范畴予以控制。在我国，制动液则实行国家工业产品生产许可证管理。来自长城润滑油公司的技术专家告诉记者，西方国家对DOT标准制定很苛刻，并非简单调配就能达到的。国内市场上很多低价劣质制动液都标明符合DOT3标准，其实产品质量并不合格。真正合格达标的制动液有几个特性：即在高温、严寒、高速、湿热等工况条件下保证灵活传递制动力；对刹车系统的金属和非金属材料没有腐蚀性；能够有效润滑刹车系统的运动部件，延长刹车分泵和皮碗的使用寿命。
    平板车车主要选好自己的制动液。
's remind: the choose and buy of brake fluid is the owner life safety, must not be so-so, brake fluid the character of the direct relationship between the reliability of the brake.

Good viscosity-temperature performance and low temperature performance braking process, because of friction fever can make the hoof temperatures as high as 250 ° C. The heat is part to brake fluid, make its working temperature of 70 ~ 90 ° C, long road conditions such as slope next driving frequent braking, its working temperature can be reached 110 ° C, and in some areas of winter brake fluid temperature and low to 40 ° C-below, therefore, ask the brake fluid has good performance and low temperature glue temperature flow properties. For the high temperature, low viscosity and low viscosity condensation point.

The good and the adaptability of the rubber in brake system in many rubber seal and skin bowl, and to keep the braking system fully closed, so the brake fluid should have good with the rubber seal of adaptability, prevent rubber seal and skin bowl for liquid oil and inflation and mechanical strength decreased.

The brake fluid its quality directly related to the safety of driving's. In 2005, nearly 100000 people have died in all kinds of traffic accident, among them ineffective, brake failure braking is one of the most important factors. Because of this, the world has always pays great attention to the supervision of the brake fluid, developed western countries are woven into the road safety regulations shall be control category. In our country, the brake fluid is a state of production license for industrial products management. The Great Wall of the company from oil technical experts told reporters that western countries the DOT standards very demanding, not simply allocate can achieve. The domestic market many low price inferior brake fluid indicated DOT3 accord with standard, in fact, the product quality is not qualified. Really qualified standard of brake fluid has several characteristics: that is in high temperature, cold, high speed, hot and humid conditions such as flexible transmission system that power; The braking system of metallic and non-metallic materials no corrosive; Can effectively lubrication braking system moving parts, extend the brake points pump and the service life of the skin bowl.

The car's main chosen their own brake fluid.
