都知道汽車的剎車是什么，油是什么，但是組合起來剎車油是什么呢？當然有車的朋友們是知道的，剎車油是用以制止車輪轉動的液體，可以說對整個剎車系統起著重要的作用。那么沃爾沃汽車的剎車油怎么會進水呢？這個問題值得了解。

　　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.

　　在正常行駛中，剎車油的溫度變化是不可避免的。剎車片與剎車盤之間的摩擦會產生大量熱量，然后通過制動缸傳遞給剎車油，剎車油升溫。如果頻繁或長時間剎車，散熱肯定不及時，剎車油溫度高，水份在高溫下不穩定，容易蒸發。問題出現在這里，如果水汽化產生空氣阻力，會阻礙剎車油的順暢流動，使剎車變軟，嚴重時甚至剎車失靈。

　　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，剎車系統實際上并不是一個完全封閉的系統——剎車油壺上有一個通氣孔，剎車油位傳感器和儲油壺之間也有空隙。車輛在涉水過程中也會導致剎車系統進水，因為剎車系統是通過諸多管件、配件連接而成的，而這些連接部位一旦稍有縫隙，那么則會導致水氣的進入。

　　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.

　　剎車油中的水很容易導致制動失效。這是因為當我們踩剎車開始剎車時，剎車片和剎車盤開始摩擦，產生大量熱量并傳遞給剎車液。在高溫高壓條件下工作，變質速度會更快，吸水達到一定量后剎車油的沸點也會降低，嚴重影響剎車效果，甚至導致剎車失靈。

　　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.

　　因此維護是關鍵，剎車片和剎車盤都是易損件，如果它們磨損嚴重但沒有及時更換，則需要更大的空間來促進剎車油驅動制動系統工作。油與空氣接觸的表面越大，就越容易產生水分。

　　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.

　　濟南沃爾沃汽車養護人員提醒大家，如果長期不更換，變質的制動油還可能腐蝕制動系統的管路，給行車帶來隱患。所以如果剎車油受潮，必須及時更換。原因很簡單，因為剎車油怕潮，嚴重影響汽車的安全。

　　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.

　　沃爾沃汽車的剎車油怎么會進水呢？這下大家都明白了吧，所以說剎車油的存在對汽車制動系統有著決定性的關系，因此呢，大家在選擇購買時還是要多方面進行考慮才是。更多內容就來網站www.junwumy.com咨詢吧！
