When should I change the brake fluid? Have you ever seen more than 180,000 or have not been replaced

I ran 70,005, I haven't changed it yet, I feel good when I press the brake pedal for a third of the time, and I won't change it for the time being to see the effect when I prepare for 100,000 kilometers. Brake fluid is actually hydraulic fluid, as long as the effect is not attenuated, you can actually ignore it. My friend's motorcycle, for more than 10 years, has never had a brake fluid changed.

The sign of the decline in brake oil is that the brake pedal feels stiff when pressed, and there is a feeling of emergency braking when braking, and the brake pedal and the whole vehicle brake are relatively smooth after changing the brake oil, and there is no feeling of frustration.

If the color of the brake fluid becomes darker, it should be considered to be replaced, and if the color is very light, there is no need to replace it.

Change brake fluid, antifreeze every two years.

Because the brake fluid will be worn out after a long time, the leather bowl and piston in the brake pump will be worn, causing the brake fluid to be turbid, so it is best to replace it.

The role of brake fluidBrake fluid is brake fluid, brake fluid is also known as brake fluid or force oil, its English name is brake fluid, is an indispensable part of braking system braking, and in the braking system, it is used as a force transmission medium, because the liquid can not be compressed, so the pressure output from the master cylinder will be directly transmitted to the sub-cylinder through the brake fluid.

Reason for replacementThe volume of the brake fluid will change with the change of temperature, so the brake fluid reservoir is equipped with a vent, and the air sucked in from the hole contains moisture or impurities, and the water will be absorbed or dissolved by the brake fluid, so the boiling point of the brake fluid containing water will be reduced. When the car is driven and braked for a long time, the temperature of the braking system rises, the brake line is easy to produce air resistance, and the air is compressed, resulting in the possibility of a decrease in braking force or brake failure. Therefore, for your driving safety, the brake fluid must be changed regularly.

How often do you change brake fluid? How do I check my brake fluid? Old Driver: Remember this time.

I drive a Toyota van in the unit, and I haven't changed the brake fluid for 7 years and 160,000 kilometers, as long as the brake fluid does not deteriorate and is scrapped.

The maintenance cycle of brake fluid is different from the official maintenance interval of each brand of car, which is related to the brand of brake fluid and the model.

Generally speaking, the brake fluid replacement cycle of the car is four years, but for some vehicles that often run in the suburbs and at high speeds, the brake pressure is relatively less, so the brake fluid replacement cycle can be appropriately extended.

However, for some medium and large cars or cars that often need to stop and stop and step on the brakes due to long-term driving in the city, the brake fuel consumption of such cars is relatively fast, so the replacement cycle is relatively short. In general, no matter what type of car it is, you must always check the wear and tear of the brake fluid and change the brake fluid according to your own situation.

How often should I change my brake fluid? How dangerous is it to go without changing for a long time? After reading it, keep it in mind.

Does it matter if the brake fluid is not changed for 6 years? Generally, the brake fluid is replaced every two years (that is, it is generally 40,000km or 2 years), if the emergency brake or frequent braking is not replaced in time, the brake fluid will be heated to boiling, and the brake fluid will accelerate the deterioration, and the boiling bubbles will be trapped in the brake pipeline to affect the braking performance, affect the service life of the locomotive and driving safety.

Precautions for changing brake fluids:

1. Before replacement, it is necessary to put on the cloth to prevent the auto parts from being corroded by brake oil.

2. Although some maintenance plants will not extract part of the old brake oil from the reservoir in advance, but in the process of draining the brake oil, the master will continue to drain the old and new mixed oil from the oil drain, and add new brake fluid in time, and repeat until the discharge is translucent yellow new oil, only to determine that the old oil is discharged, of course, this will use more new brake oil.

3. Pay attention to the complete exhaust of air when replacing the brake oil, once the brake pump of the brake system and the hydraulic oil pipe of the state bend enter the air ruler, it will reduce the braking performance of the car and seriously affect the driving safety. The oil guide pipe should be transparent and clean, which can judge the discharge of old oil and observe whether there are bubbles.

If the brake fluid is not changed for a long time, the braking distance will become longer, and the brake oil pipe will corrode and leak oil.

Vehicle brake fluid is also called brake fluid, brake fluid. It is a fluid that is suitable for the hydraulic brakes of vehicles. Because its quality has a great relationship with the reliability of brake socks and slippery, the choice of brake fluid affects the lives of drivers and passengers, and it must not be sloppy.

Therefore, it is essential to know the signs of a lack of brake fluid and how to operate it correctly.

Under normal circumstances, every two years, forty or fifty thousand kilometers, the brakes must be replaced. However, there are quite a few veterans who scoff at this, because there are quite a few people who have not changed the brakes and brakes at all, why is this happening?

In fact, such a thing is not uncommon, and the brakes are generally replaced once in two years or so, but if it is in a 4S shop, it is too easy, after all, the car is just a means of transportation, buy one here, that is a car that is more delicate than people. Because the brake fluid is basically ethanol and absorbent, its moisture content will gradually increase in long-term applications.

After one year, the moisture content in the brake fluid will exceed 3%, if the moisture content in the brake fluid exceeds a certain value, then the braking force will become smaller, and the braking time will become longer, this cycle is different, different car manufacturers will be different according to different brands and models of brake fluid, because the brake fluid itself has a certain corrosiveness and water absorption, so many repair shops will be equipped with special instruments to test the moisture content of the brake fluid, and then test to determine whether to replace. When repairing, the brake fluid should be changed frequently, and it is recommended to repair it according to the manufacturer's requirements.

Normally, we think that the brake is closed, but in reality, there are still many ways to mix the inlet water in the brake fluid. In the brake, the water flow is the least favorite one, one is eroded by the seawater, and the other is that the water temperature is too high, which is likely to vaporize, which will lead to problems with the braking system, which is the cancer of the brake. When water is added to the brake fluid, its boiling point drops by an astonishing 60 to 90 degrees Celsius.

Typically, after 2-3 years of use, the moisture content of the brake fluid will exceed 3%.

I think of course it needs to be replaced, normally every two years or so, and it doesn't need to be too often.

I think it needs to be replaced, because if it takes a long time, it will probably emit a foul smell and become less impactful.

I think of course you have to change it, because the brake fluid will also deteriorate, which will affect the braking effect.

The brake fluid needs to be replaced after a certain period of time, and it is not necessary to replace it if there is nothing to do. Brake fluid is similar to engine oil, it has an expiration date, and the effect will be reduced after the expiration date. The water absorption of brake fluid is very strong, and the brake system is not a completely closed environment, and the water content of the brake fluid will exceed the standard after being used for a long time.

If the moisture content of the brake fluid exceeds the standard, the boiling point will be reduced, which may lead to the failure of the brake. The brake oil will become dirty and deteriorate after a long time, and the brake master cylinder and sub-cylinder will be worn to a certain extent, and there will be oil leakage when it is serious, and once the oil leaks to the brake disc or brake pads, the brake will fail.

Does it matter if the brake fluid is not changed for 6 years? It is very important that the brake fluid is not replaced for 6 years. The slower and wider change cycle of brake fluid is generally used for two years or 40,000 kilometers, and the brake fluid should be replaced three times in 6 years, and the replacement cycle will not have much impact on the vehicle if it exceeds the regulations too much, which will not only cause wear and tear to the vehicle, but also affect the safety of the people in the car. The brake fluid is originally light yellow and very translucent, and after 6 years of use, the brake fluid will be like espresso, and its effect will be seriously invalid.

Different brands and different types of brakes should not be mixed, although it is brake oil, but their main components are not the same, which will lead to a decrease in brake oil index, reduce the effect, and even react to produce impurities to cause wear and tear on the brake system.

1. No, you cannot.

2. If the brake oil is not changed for a long time, the water content will increase and it will age. The brake fluid is aging and can easily cause brake failure. The high moisture content of the brake fluid makes it easier for the piston of the brake pants to jam.

3. The old oil is dark green with wide color with obvious deposition, and it is slightly turbid, and the brake fluid is not good enough, which will corrode and burn the leather plug in the brake oil pump, resulting in a reduction in the braking effect.
