A precursor to a need for a brake fluid replacement? What are the warning signs that the brake fluid

The precursors of a brake fluid replacement are:

During emergency braking or continuous braking, the brake indicator light flashes intermittently, which is due to the reduction of brake oil, and it is necessary to detect and replace it in time, otherwise it will affect the braking effect; When the car is driving normally to a speed of more than 40km per hour, the braking distance becomes longer, and the brake pads are excluded from the factors, which is a problem with the brake fluid.

If you accidentally mix gasoline, diesel oil or glass water into the brake fluid, it will greatly affect the braking effect. It should be replaced in a timely manner. If the vehicle drives normally for 40,000 kilometers or the brake fluid is used continuously for more than 2 years, the brake fluid is easy to deteriorate due to long use, so it is necessary to pay attention to replacing it in time.

The brake fluid is generally replaced once every 2 years and about 4w kilometers.

1. When emergency braking, or continuous braking, the brake indicator light alarms and flashes, but intermittently, the alarm light comes and goes, sometimes it lights up after braking, but it runs for a period of time and is gone, at this time it is generally the reason for the reduction of brake oil, and it must be detected and replaced in time, otherwise it will affect the braking effect.

2. When the car is driving normally to a speed of more than 40km per hour, slam on the brakes, and the braking distance becomes significantly longer. In addition to excluding the factors of brake pads, it can basically be concluded that there is a problem with the brake fluid.

3. The brake pedal feels abnormal, such as softness and weakness, which is generally the deterioration of the brake fluid, and the brake pedal will give people a soft feeling even if it is stepped on to the end, especially after continuous and frequent braking, the feeling of stepping on the brake pedal will be much softer than before, and it is elastic.

4. The brake pedal will be soft when pressed, and the deterioration of the brake fluid will make the brake pedal give people a soft feeling even if it is pressed to the end. Especially after continuous and frequent braking, the feeling of pressing the brake pedal will be much softer and more elastic than before.

1. The brake fluid turns black. When the brake fluid turns black, it means that impurities have entered it. In this case, it should be replaced in time, otherwise it is easy to cause brake fluid blockage, which will further affect driving safety.

2. Weak brakes. When you feel a lack of brake power, it means that there is a problem with the brake system, and if the brake fluid is missing, a similar problem can occur. In this case, it is necessary to go to the repair shop or 4S shop to find a professional for inspection, and the specific problem is analyzed in detail.

3. The age of the car is too long. When the car has been driven for a certain year, it is best to replace it from a safety point of view, regardless of whether the brake fluid is missing or not.

If the brake fluid is not changed, the braking force will decrease, resulting in air resistance in the brake line, which will affect the performance of the brake. It can also corrode the brake line, causing damage to the internal valves of the anti-lock brake hydraulic assembly, which seriously affects the transmission response of the brakes. If the brake fluid is used for a long time, it will also cause the leather bowl and piston in the brake pump to wear out, resulting in turbidity of the brake oil.

Brake fluid is a solution that is easy to mix with water, in the process of long-term use, there will be some water or impurities from the hole on the oil storage tank into the hole, and water mixed will cause the boiling point of the brake fluid to be greatly reduced, once it reaches a certain extent, when the owner uses the brake system, there may be a lot of gas resistance due to high temperature evaporation in the pipeline, at this time the braking force will drop significantly and may even fail, and the risk of driving will increase.

The precursors of brake fluid need to be replaced are: flashing alarm, longer braking distance, and deterioration of brake fluid.

1. Flashing alarm: In the case of continuous braking or emergency braking, there will be intermittent flashing alarm of the brake indicator, which is due to the reduction of brake oil, and it is necessary to detect and replace it in time, otherwise it will affect the braking effect.

2. The braking distance becomes longer: when the car is driving normally and the speed reaches 40km per hour, the brake is slammed, Mu Hui will find that the braking distance has become longer, if it is not the brake pads, it is a problem with the brake oil.

3. Deterioration of brake oil: When the brake fluid deteriorates, the feeling of stepping on the brake pedal is soft, even if it is stepped on to the end, and after continuous and frequent braking is bright and sensitive, the feeling of stepping on the brake pedal is softer and more elastic.

Brake fluid selection tips

1. The type of brake fluid selection: the owner should try to choose synthetic brake fluid instead of the alcohol brake fluid that has been eliminated.

2. Where to buy brake fluid: It is recommended that car owners should buy brake fluid from qualified chain stores or manufacturers who have provided supporting brake fluid to automobile factories for a long time, so as to ensure that they can buy products with stable performance and high quality.

3. The grade of brake fluid: Generally speaking, the higher the grade of brake fluid, the higher its quality, and the more stable its performance is. Therefore, it is recommended that mid-to-high-end models choose brake fluid that meets the HZY4 standard, while cars of micro and low-end models can choose HZY3 standard brake fluid.

4. The color of the brake fluid: Usually the good quality brake fluid should be dark yellow or light yellow, so the owner can choose according to the color of the brake fluid, remember not to choose the brake fluid with thin and transparent oil.

The precursor to the need to change the car oil is that the brake fluid is dirty and turns black.

Brake softness: because the brake fluid has a certain water absorption, in the process of its use, it will continue to absorb the moisture in the surrounding air, if the brake fluid is used for too long, the absorption of water is too high, then during braking, due to the high temperature may produce air resistance in the pipeline of the brake system, thereby affecting the brake effect, and even cause direct failure of the brake.

Generally, if the brake fluid is mixed with water, it is easy to deteriorate, and the brake fluid will affect the braking effect of our car because of the excessive water content, so this brake fluid is not a joke, we must pay attention to it.

The signs that the brake fluid needs to be replaced are as follows:1When braking in an emergency or continuous braking, the brake indicator flashes intermittently.

This is because the brake fluid is reduced, and it needs to be detected and replaced in time, otherwise it will interfere with the braking effect; 2.When the car is driving normally at a speed of more than 40 kilometers per hour, it will slam on the brakes and the braking distance becomes longer. In addition to the factor of brake pads, there is also the issue of brake fluid.

During emergency braking or continuous braking, the brake indicator will alarm and flash, but the warning light will not be intermittent or sometimes illuminated. Sometimes I get on after braking, run for a while and then it's gone. At this time, the brake fluid is usually reduced, and it needs to be detected and replaced in time, otherwise it will interfere with the braking effect.

When the car is driving normally at a speed of more than 40 km/h, the braking distance becomes significantly longer. In addition to the brake pads, it can basically be concluded that there is a problem with the brake fluid. When you press the brake pedal, you will feel abnormal, such as feeling weak.

This is usually the case of brake fluid deterioration. Even pressing the brake pedal all the way down gives it a soft feel. Especially after continuous and frequent braking, the feeling of pressing the brake pedal will be much softer and more elastic than before.

Pressing the brake pedal will make it soft, and the deterioration of the brake fluid will make the brake pedal feel soft even if you press it all the way. Especially after continuous and frequent braking, the feeling of pressing the brake pedal is much softer than before, and the elasticity is also greater.

The key is that the brake fluid is mixed with water, which causes the moisture content of the brake fluid to exceed the standard, if it is operated at high temperatures, the water in the brake fluid will become water vapor, which endangers the braking effect, which is very dangerous. Therefore, it is necessary to check regularly and change the brake fluid immediately.

There are three key signs that the brake fluid must be replaced:

1. In the case of continuous braking or emergency braking, there will be an intermittent flashing alarm of the brake indicator light, which is because the brake fluid is reduced, and it is necessary to carry out inspection and replacement immediately, otherwise it will endanger the effect of the brake pedal.

2. When the vehicle is driving normally and the speed reaches 40km h, you will find that the braking distance is extended.

3. When the brake fluid is mildewed, the feeling of stepping on the brake pedal is weak, even if it is stepped on in the end, this is the case, and after continuous and frequent brake pedal, the experience of stepping on the brake pedal is softer and malleable.

Some people regret changing the brake fluid, it may be that the effect of the brake pedal decreases after the change, and it will feel softer when you press the brake pedal. The root cause may be the presence of vapor in the oil pipe, followed by the quality of the brake fluid that is likely to be replaced. Generally, after replacing the new brake fluid, the braking effect will be better, if the effect is not good, you should check with the repair shop, and then re-test its shortcomings.

The general situation is to change the brake fluid once every 2 years, and some manufacturers require more than 40,000 kilometers to be replaced up and down, but this is used as a reference, and the actual situation needs to be taken into account.

The precursor of the need to change the brake fluid is: the brake fluid is dirty and turns black. Brakes softened:

Because the brake fluid has a certain water absorption, in the process of its use, it will continue to absorb the moisture in the surrounding air, if the brake fluid is used for too long, the water absorbed is too high, then during braking, due to the high temperature, it may produce air resistance in the pipeline of the brake system, thereby affecting the braking effect, and even cause direct failure of the brake.

Generally, if the brake fluid is mixed with water, it is easy to deteriorate, and the brake fluid will affect the braking effect of our car because of the excessive water content, so this brake fluid is not a joke, we must pay attention to it.

How often should we change the brake fluid? Generally speaking, there is no fixed replacement standard, generally if our car has traveled about 60,000 kilometers can be replaced with brake fluid, so how should we make sure that the brake fluid has deteriorated? In fact, it is also very simple, there is generally a brake fluid test pen now, you can buy one yourself, and regularly test the car at home, which is when you can know when you should change the brake fluid.

The precursors of the need to change the brake fluid mainly include intermittent flashing alarm of the brake indicator in the case of emergency braking; Emergency braking is adopted, and the braking distance is significantly longer than before; The brake pedal is soft when pressed; When braking, the braking force feels light and heavy. The reason why the brake fluid needs to be replaced: the brake fluid has been used for a long time, and it is irritated and deteriorated or precipitated, because the brake fluid has a certain water absorption, and will continue to absorb the moisture in the surrounding air during its use.

Therefore, it is necessary to change the brake fluid in time or equip it with a brake fluid that is more suitable for car use. Brake fluid replacement cycle: The usual situation is to change the brake fluid once every two years or so, and some manufacturers stipulate that it is about 40,000 kilometers to replace it.
