Some car owners always like to brag about themselvesBrake FluidIt has not been changed until it is scrapped. Xiaobai, who blindly saves money, has already begun to follow suit, but others have dump trucks and enough insurance. Will your family car dare to fight like this? Failure to change the brake oil directly affects the performance of the braking system. At speeds above 60km/h, when driving on the road at a fast speed, the failure of the brakes will be a tragedy of car crashes every minute.
The role of brake fluid
In short, brake fluid is the medium of the brake system. Under the support of the vacuum booster pump, the amplified pressure pushes the brake master cylinder to release the brake fluid, which flows to each brake cylinder through the pipeline. Under the pressure of the brake fluid, the brake pads will compress the brake disc, and the brake effect is achieved at this time. The following animation demonstrates the working principle of drum brakes and disc brakes.
How often should the brake fluid be changed?
The normal use time is2 years or 40,000 kilometers, But it depends on the use of the vehicle and the driving environment. Brake fluid has strong water absorption, so intermittent bubbles will form in the pipeline after a long time of use. These bubbles are the culprit for the ineffective travel, which is the reason why the car owner sometimes does not respond when he brakes.
The northern weather is dry, and the cycle can be extended appropriately according to the oil condition. The humid weather in the south is more serious, and there is too much moisture in the air. You can maintain the brake fluid in advance.
Look for opportunities to replace brake oil from these precursors
1. There is a problem with the quality of the brake fluid. It can be seen from the brake fluid tank that the fluid has turned black and dirty.
2. When the owner performs continuous braking or emergency braking, the brake light on the dashboard flashes intermittently, and the vehicle disappears after a period of time.
3. When braking at medium and high speeds, the braking distance becomes significantly longer. If it is not the reason for the wear of the brake pads, there is a high probability that the brake fluid is the problem.
4. The brake foot feels abnormal, soft and weak. In severe cases, there is still not much resistance feedback when you step on the brake pedal to the end. The soft foot feeling can basically be concluded as a brake fluid problem.
5. Leaking brake fluid. At this time, it is not only necessary to replace the brake fluid, but also to repair the damaged oil circuit or loose joints. This situation is very serious and I didn't feel much about driving at the beginning. With the dripping of oil, the brake performance deteriorates and finally leads to complete failure.
☀High-tech introduction☞Automobile brake oil detection pen
It has a very unique and elegant name:[Brake Pen]. The owner can buy it online at a price of 20Yuanabout. It can be judged mainly by the lighting conditions of 5 parameters:
① 0%:There is almost no water in the brake fluid, so you can sit back and relax for the time being. (Perfect)
② 1%:The proportion of water is less than 1%, and it can continue to gallop. (qualified)
③ 2%:The proportion of water is less than 2%, and there is a hint of danger. (qualified)
④ 3%:The proportion of water is less than 3%, and the brake oil needs to be replaced in time. (Unqualified)
⑤ 4%:The proportion of water is more than 4%, the invalid stroke caused by air bubbles increases, and the brake fluid must be replaced immediately. (Unqualified)
