How to change the brake fluid, the basic steps to replace the brake fluid

When it comes to car maintenance, I believe that many car owners attach great importance to it. It can be said that timely replacement of oil, air and air-conditioning filters can be said to be commonplace.But whenBrake FluidThis aspect is often overlooked by everyone. In fact, it also needs to be replaced regularly. After all, the quality of the brake fluid directly affects the braking effect. So how do you change the brake oil, and what needs to be paid attention to when changing.

replaceBrake fluidThe basic steps:

1. First, put the vehicle in a flameout state, open the lid of the brake fluid pot, and use a syringe to draw out all the brake fluid inside until there is no more at the bottom of the tank.

2. Then you can pour the new brake fluid into the fuel tank (1-2L). As for how many liters to fill, it depends on the fuel tank capacity.

3. Use a lift to raise the bottom of the car. Of course, we can also use a jack, but it is not so convenient to operate.

4. Then find the oil drain screw of the brake cylinder, and remove the dust cap on the oil drain button.

5. Use a wrench to loosen the drain screw, put the rubber tube on it, and connect the other end to the drain bottle.

6. At this time, you can start to step on the brakes. Pay attention to the color of the brake fluid in the rubber tube. If the color is still relatively dark, it proves that the old brake fluid has not been drained. And if the color is relatively light, it means that the tire has been changed oil, stop stepping on the brakes and install the screws and dust caps back (the other three tires are also operated in the same way).

But in this process, it is best for one person to be responsible for stepping on the brakes, and the other for observing the color, so as to avoid accidentally letting out all the oil in the oil tank and causing air to enter the brake system.

7. Finally, you need to observe the position of the brake fluid level. If it is lower than the lowest scale line, you need to replenish the brake fluid.

But it should be noted that in the process of replacing the brake fluid, you must be careful that the fluid splashes on your skin, because the brake fluid is very corrosive and can easily damage the surface of the skin. Needless to say, if it splashes into the eyes, it must be rinsed with a large amount of running water to dilute the chemical substance concentration to the lowest possible level. If your eyes become red and swollen and feel very painful, you need to seek medical attention in time.
