Why change the brake oil?

Car maintenance is something that every car owner should do regularly after buying a car, so the correct and scientific maintenance of the car is conducive to improving the service life and driving experience of the car. It goes without saying that some routine maintenance is well known, but some unconventional maintenance will be ignored by most car owners and even old drivers, such as changing spark plugs, transmission oil, steering power oil and brake oil. Today, I will take you to understand why brake oil should be replaced regularly and how to correctly judge whether brake oil needs to be replaced.

The role of brake oil What does brake oil usually do? When the driver steps on the brake pedal during driving, the brake booster pump will provide braking power. He is like a Hercules, helping the driver to brake, pushing the brake master cylinder and pushing the oil in the fuel tank into the ABS pump. The ABS pump then distributes the oil pressure to the four wheels through four oil pipes. Let's take the former driver as an example. Generally speaking, the oil pressure is distributed to the front wheels a little more and the rear wheels a little less. This is the braking force obtained by the cylinder on the caliper, which plays the role of safe braking.

Why do you need to change brake oil regularly? After long-term use, it will enter the ash layer, and impurities and moisture will cause brake oil to deteriorate. The biggest problem of brake oil in use is that it especially likes to absorb moisture in the air. As we all know, once water meets high temperature, it will produce steam. Because the brake system is sealed, the steam can't run out and wander around in the oil pipe, thus forming a section of gas, which is easily compressed, so part of the pressure in the oil pipe will compress the gas and become empty. Therefore, for the safety of yourself and others, it is necessary to change the brake oil regularly.

How do you know whether to change the brake oil 1? Let me teach you a stupid way first, that is, according to the maintenance manual, there is a clear replacement cycle on it, and the owner just has to obey and do it, but the replacement cycle in the maintenance manual, hehe. 2. Teach you an advanced method to make your bronze king more like an old driver. Open the brake oil pot cover to see if the brake oil is turbid. If it is turbid, please replace it. If it is clean, measure the water content of brake oil with a brake oil test pen. If the water content exceeds 3%, please replace it. This method can save you some tickets. In short, it is recommended that the owner look at his maintenance manual to see if there are any items that have been ignored in the replacement cycle. During routine maintenance, they can check and see if they need to be replaced. After all, safety comes first.
