Do I need to change the brake fluid to change the brake pads? The brake fluid becomes soft after changing the brake pads

What we talked about todayBrake FluidAnd brake pads play a vital role in the braking system. Then some netizens responded that when replacing the brake pads, the brake fluid also needs to be replaced, because the two are complementary to each other. So is the fact really the case? Does the brake oil need to be changed to change the brake pads?

There is no need to change the brake fluid when changing the brake pads, because their replacement cycle itself is different. The brake pads should be checked every 5,000 kilometers. Not only the remaining thickness, but also the wear status of the shoes should be checked. If there is a problem, it needs to be dealt with in time. The brake oil is generally replaced every 2 years or 40,000 kilometers, which is much longer than the brake pads. Of course, we have to decide based on the real-time situation. If you feel that the texture of the brake is significantly softer, or even feel that the car cannot be stopped, then you have to check the water content of the brake fluid. If it exceeds 3%, it needs to be replaced in time. .

As for the reason why the brake fluid has become soft after changing, it is most likely that an error occurred during the replacement process, which caused air to enter the brake fluid pipe and the air needs to be discharged in time. At this time, two people have to cooperate. One person is responsible for stepping on the brakes (repeatedly stepping on it many times), while the other person loosens the bleed screw on the brake cylinder. If there is air, a part of the brake fluid and gas. If all the brake fluid is sprayed out, it means that all the gas in the brake hose has been exhausted, and finally tighten the bleed screw directly.
