Cars need to add a variety of oil to operate normally, and the most familiar to car owners is probably the oil, so they often check the status of the oil and replace it regularly. However, in addition to the oil, there are many oils, such as transmission oil, steering oil, brake oil and so on. Their state is also related to the normal operation of the vehicle, but the replacement cycle will be longer, and it is often forgotten by the owners, and when the problem is found, it will only be more difficult to repair, and the maintenance cost is naturally not cheap.
Next, let's take a look at the replacement of brake fluid, which is often ignored by car owners, and the sense of existence is not strong. Some people say that it can even not be changed for life, so how often should it be replaced. First of all, we must be clear that no matter which kind of oil can not be changed for life, in the process of long-term use of the oil will be consumed, losing its original role, and then affecting the normal operation of the vehicle.
The importance of the braking system for driving safety is clear to everyone, and the brake oil is the medium that drives the brake calipers, and the two are like the relationship between fish and water. Without water, fish cannot survive. In order for the fish to survive better, people need to change the water in the fish tank regularly, and the same is true for the brake fluid.
With the passage of time, the brake fluid will slowly fail and deteriorate, and it will not play its due role, which will directly affect the foot feel of the brake system and the service life of the brake pad brake disc. As for why the brake fluid deteriorates, it is because it has water absorption characteristics, if the moisture content of the brake oil is too high, it will reduce the reliability of the brake, and it will cause a car accident if it is serious.
If the brake fluid is abnormal, under normal circumstances, the owner cannot feel it, which is very dangerous. Vehicles with an age of more than 5 years can basically reach 7% of the water content of brake oil. The moisture content of the brake oil is only less than 5%, so that it will not affect the brake system. Therefore, the replacement cycle of brake oil needs to be replaced once in two years or between 40,000 and 50,000 miles.
Of course, this replacement cycle can only be used as a reference, because the ambient humidity of the vehicle will also affect its state, and the replacement cycle in the tropics will be shorter. For the replacement cycle of brake fluid, there will be clear instructions on the car manual, and the owner can replace it with reference to the manual. The owner can tell if it needs to be replaced by the color of the brake oil.
The color of the new brake oil is pale yellow, which looks more thorough and has no impurities. As the use time increases, the color of the brake oil will be significantly darkened and some impurities will be generated, which may need to be replaced. There is a slow process of brake oil deterioration, and it will not be completely without braking force after deterioration. It's just that when the owner steps on the brakes, he will find that the brake foot feels soft.
Once this situation is encountered, the owner needs to immediately check the status of the brake oil and replace it in time so as not to affect the safety of driving. The cost of replacing the brake oil is not expensive, although it does not need to be replaced frequently, but everyone can not ignore it, after all, there is no small matter related to safety, it must not affect safety because of it, once it leads to a traffic accident, it is too late to regret it. Of course, everyone sometimes don't listen to the 4S shop flickering, so as not to spend money unjustly.
