都知道汽车的刹车是什么，油是什么，但是组合起来刹车油是什么呢？当然有车的朋友们是知道的，刹车油是用以制止车轮转动的液体，可以说对整个刹车系统起着重要的作用。那么沃尔沃汽车的刹车油怎么会进水呢？这个问题值得了解。

　　We all know what the brakes are and what the oil is, but what is the combined brake oil? Of course, car friends know that brake oil is used to stop the wheel rotation of the liquid, can be said to play an important role in the entire brake system. So how did the Volvo's brake fluid get water? The question is worth knowing.

　　在正常行驶中，刹车油的温度变化是不可避免的。刹车片与刹车盘之间的摩擦会产生大量热量，然后通过制动缸传递给刹车油，刹车油升温。如果频繁或长时间刹车，散热肯定不及时，刹车油温度高，水份在高温下不稳定，容易蒸发。问题出现在这里，如果水汽化产生空气阻力，会阻碍刹车油的顺畅流动，使刹车变软，严重时甚刹车失灵。

　　In normal driving, the temperature change of brake oil is inevitable. The friction between the brake pad and the brake disc generates a lot of heat, which is then transmitted through the brake cylinder to the brake oil, which heats up. If you brake frequently or for a long time, the heat dissipation will not be timely. The temperature of brake oil is high, and the water is unstable and easy to evaporate under high temperature. The problem is that if the water vaporizes and creates air resistance, it can prevent the smooth flow of brake oil, making the brakes soft and, in severe cases, even brake failure.

　　此外，刹车系统实际上并不是一个完全封闭的系统——刹车油壶上有一个通气孔，刹车油位传感器和储油壶之间也有空隙。车辆在涉水过程中也会导致刹车系统进水，因为刹车系统是通过诸多管件、配件连接而成的，而这些连接部位一旦稍有缝隙，那么则会导致水气的进入。

　　In addition, the brake system is not actually a completely closed system -- there is a vent hole in the brake oil can and a gap between the brake oil level sensor and the oil storage can. The vehicle in the process of wading will also lead to water in the brake system, because the brake system is connected by a lot of pipe fittings and accessories, and once there is a slight gap in these connection parts, then it will lead to water entering.

　　刹车油中的水很容易导致制动失效。这是因为当我们踩刹车开始刹车时，刹车片和刹车盘开始摩擦，产生大量热量并传递给刹车液。在高温高压条件下工作，变质速度会更快，吸水达到一定量后刹车油的沸点也会降低，严重影响刹车效果，甚导致刹车失灵。

　　Water in the brake oil can easily lead to brake failure. That's because when we hit the brakes and start braking, the brake pads and the brake disc rub together, generating a lot of heat and transferring it to the brake fluid. Working under high temperature and high pressure conditions, the deterioration rate will be faster, and the boiling point of the brake oil will be reduced after the water absorption reaches a certain amount, which will seriously affect the braking effect and even lead to brake failure.

　　因此维护是关键，刹车片和刹车盘都是易损件，如果它们磨损严重但没有及时更换，则需要更大的空间来促进刹车油驱动制动系统工作。油与空气接触的表面越大，就越容易产生水分。

　　Therefore, maintenance is the key, brake pads and brake discs are vulnerable parts, if they are badly worn but not replaced in time, you need more space to promote the brake oil driven brake system to work. The more surface the oil is in contact with the air, the more likely it is to produce moisture.

　　济南沃尔沃汽车养护人员提醒大家，如果长期不更换，变质的制动油还可能腐蚀制动系统的管路，给行车带来隐患。所以如果刹车油受潮，必须及时更换。原因很简单，因为刹车油怕潮，严重影响汽车的。

　　Ji 'nan Volvo car maintenance personnel remind you that if you do not replace for a long time, the deterioration of the brake oil may also corroded the brake system pipeline, to bring hidden dangers to driving. So if the brake oil is damp, it must be replaced in time. The reason is very simple, because the brake oil is afraid of moisture, seriously affect the safety of the car.

　　沃尔沃汽车的刹车油怎么会进水呢？这下大家都明白了吧，所以说刹车油的存在对汽车制动系统有着决定性的关系，因此呢，大家在选择购买时还是要多方面进行考虑才是。更多内容就来网站www.lutongqixiu.com咨询吧！
