How often is brake maintenance recommended?

Car brakes are not delicate objects, and the time limit is not fixed, in addition to the quality of the vehicle, it is more dependent on the driving environment and driving habits. 1. Brake pads. Brake pads are parts that are frequently replaced, and they also play a great role in changing the driving experience.

In general, you need to replace the brake pads every 30,000 kilometers driven, but in real life, you need to refer to your daily driving environment, the driver's driving habits, etc. If you live in a mountainous and hilly area, or you have the habit of overtaking and frequently applying the brakes, you need to change the brake pads every 10,000 kilometers or so. When the brake pads need to be replaced, the driving computer of the general high-end car will prompt, and when you find that the dashboard prompts that the brake pads need to be replaced, you can replace them as soon as possible.

Another intuitive method is to check the thickness of the brake pads. The thickness of the new brake pads is about 1.5 centimeters, and when you notice that only a third of the brake pads are worn, or if you feel that the brake feet are soft, and the braking distance is significantly longer than expected, and there is a significant gap between the new brake pads, it is time to replace the brake pads. Second, the brake disc.

When the owner reads the maintenance manual, he will find that there is no item about the brake disc in the daily maintenance, because if the brake disc can generally be used for life. Brake discs have a long service life, but they also require the right daily maintenance methods. For example, if you have just finished driving at high speed and the brake system, including the brake disc, is still in a high temperature, please do not wash the car immediately, as thermal expansion and contraction will shorten the service life of the brake disc.

In addition, please do not apply lubricating products to the brake disc, as this will cause brake failure. 3. Brake fluid. The instruction manual that comes with your car clearly indicates the replacement period of the brake fluid in the braking system, which is generally two years or 40,000 kilometers, and the two indicators come first.

Because brake fluid has an obvious effect on the braking effect, it is recommended to replace the product with higher quality. Generally, car repair shops use the method of manual replacement of brake fluid, which is not as hygienic as special machines, so it is recommended that you complete the replacement of brake fluid in a 4S shop, or try to choose a repair shop with brake fluid replacement machine.

Brake pads need to be changed once for 3 to 60,000 kilometers. In the braking system of a vehicle, the brake pads are the most important object, and the quality of the brakes is determined by the brake pads.

The braking system is deeply maintained every 20,000 kilometers.

Brake fluid also has a shelf life with other lubricants, for safety reasons, it is okay to change the brake fluid every two years, if it is considered okay by the 4S shop. If there is a slight noise when braking, it is generally not a big problem, but if there is an obvious abnormal noise or shaking when braking, it is necessary to carefully check or repair the brake disc (drum) and brake pads.

Disc brakes are prone to problems, generally about 5-60,000 kilometers; Drum brakes are prone to problems, generally around 80,000 kilometers. Of course, if it is used properly or of excellent quality, the service life can be appropriately extended.

The main components of the brake system.

1. Brake disc diameter.

The diameter of the brake disc d should be as large as possible, and the effective radius of the brake disc is increased, which can reduce the clamping force of the brake caliper, and reduce the unit pressure and working temperature of the pad. Limited by the rim diameter, the diameter of the brake disc is usually selected as 70% to 79% of the rim diameter. Cars with a total mass greater than 2t should take the upper limit.

2. Thickness of brake disc.

The thickness of the brake disc has an impact on the quality of the brake disc and the temperature rise during operation. In order to make the mass smaller, the thickness of the brake disc should not be very large; In order to reduce the temperature, the thickness of the brake disc should not be too small. The brake disc can be made solid, or a ventilation hole can be cast in the middle of the disc for heat dissipation and ventilation.

Generally, it is 10,000 kilometers of normal maintenance, 5,000 kilometers to change the oil when checking, more than 40,000 kilometers to check whether the brake pads need to be replaced, change the brake oil.

The disc front wheel is about 30,000 kilometers; disc rear wheel about 60,000 kilometers; The drum brake is about 100,000 kilometers.

It is recommended to do a brake depth maintenance every 20,000 kilometers, brake oil and other lubricating oils have a shelf life, for the sake of safety, it is okay to change the brake fluid every two years, disc brakes are prone to problems generally in about 5-60,000 kilometers, drum brakes are prone to problems in about 80,000 kilometers.

During use, the brake fluid absorbs water from the air and lowers its boiling point from 260 to 150. The boiling point of a low-quality brake fluid drops more severely at the same time. Brake pad and brake disc (drum) friction and produce braking force, this high-speed friction will produce high temperature up to 800, high temperature will quickly be conducted from the brake pad to the brake oil, if the brake process due to high temperature caused by the brake oil boiling, will cause the brake braking force to decrease or disappear, resulting in brake failure, danger.

Therefore, when the boiling point of the test brake fluid is below 180 for the main cylinder or below 150 for the sub-cylinder, the brake fluid has deteriorated and must be replaced. Improving driving safety and reducing the occurrence of traffic accidents is the most important purpose of braking system maintenance.

During the routine maintenance of the vehicle, if the maintenance technician does it carefully, he will grind the oxide on the surface of the brake pad, measure the thickness of the brake pad and brake disc, and detect whether the brake caliper moves smoothly, so that the abnormal situation of the braking system can be dealt with in time. Drum brakes, the advantage is that the brake strength is large, the manufacturing cost is low, the maintenance cost is low, basically there is no special situation, no need to replace parts, and the disadvantage is that the brake device is in a relatively closed environment, and the temperature generated by the brake is difficult to dissipate.

Brake failure or failure can be caused by severe thermal degradation of the brake disc due to frequent braking, severe wear of the brake pads, or it may be that the brake fluid is too dirty and needs to be replaced. It is also necessary to pay attention to check whether the brake disc is seriously worn, and the quality of the brake fluid directly affects the braking efficiency of the braking system. Inferior brake fluid not only has a low boiling point, but also has the potential to corrode metal pipes and accelerate the aging of rubber parts.

In view of this, it is recommended to go to a regular 4S shop to change the brake fluid. Nowadays, basically all family cars on the market use hydraulic brake systems, you can think of this system as a needle tube with a small opening, when there is no air in the needle, then you will feel very difficult.

For the brake system, the maintenance of the brake system is mainly for the corresponding inspection and cleaning of the brake inspection, and the main items are including brake disc cleaner, cylinder, etc. Today, there is a comprehensive range of cleaning and lubrication for the components of the brake system. Brake shoes should ideally be inspected every 10,000 kilometers and replaced if they are about to wear or have exceeded the limit.

There is a brake fluid moisture measuring instrument on the market, directly open the oil filler of the brake oil, put the measuring instrument in, if the moisture content is less than 3%, it means that there is no problem, if it is between 3% and 5%, you need to take time to change the brake fluid immediatelyRecommendation: Maintenance every year or 20,000 kilometers.

It is necessary and generally every three months is appropriate. Because the vehicle's braking system still needs to be maintained, if it is not maintained, it is easy to have an accident.

Of course, it is necessary to do maintenance, and it is generally more appropriate to do it once a year or so, because brake pads are also a consumable.

It is necessary to maintain the mileage, it is generally believed that the front brake pads should be replaced every 30,000 kilometers, and the rear brake pads should be replaced every 5-60,000 kilometers, but because the weight of various models, the use of load, and road conditions are not the same, so the wear is different, therefore, even if it is not replaced, it is necessary to increase the frequency of self-inspection outside this mileage range to eliminate hidden dangers.

Car brake maintenance is judged based on the kilometers you drive, as follows: Debate Sparrow.

1. Under normal circumstances, you need to replace the brake pads every 30,000 kilometers, but in real life, you need to refer to your daily driving environment, driving habits, etc.;

2. If you live in the mountainous hill town brother tomb area, or the royal stove raider, you have the habit of overtaking, often step on the brakes, and you need to replace the brake pads at about 10,000 kilometers;

3. If you find that only one-third of the brake pads are worn, or you feel that the brake feet are soft and the braking distance is significantly longer than expected, then you should replace the brake pads.

<> car brake is a part of the car braking system, but also one of the guarantees of driving safety, it can be seen that the importance of brakes, without the brake is like a fierce horse off the reins, the consequences will be very serious, then, should the brake be maintained?

1.Failure of the braking system.

When the braking system fails, it is more harmful, not only making the vehicle unable to slow down or stop, but also causing traffic accidents.

2.Poor braking effect.

When the braking effect is relatively poor, the deceleration effect of the vehicle after braking is relatively small, and the braking distance is significantly larger than the normal range. When judging such faults, the hardness and stability of the brake disc when depressing are the basis for judgment.

3.Brake shake failure.

One of the common faults in braking systems is brake shake failure. There are many reasons for brake jitter failure, such as obvious deformation of brake pads and insufficient flatness of brake discs.

So, what can we do about brake maintenance?

1.Change the brake pads regularly. Severe wear and tear of the brake pads can lead to brake failure and brake failure. Therefore, the wear of the brake pads should be checked regularly and replaced in time.

2.Regular maintenance. After the vehicle has traveled a certain mileage, the driver should regularly maintain the vehicle, such as checking the height of the brake oil and replacing the brake fluid in time; If impurities or darkening are found when changing the brake fluid, it is an indication that a contaminant has contaminated the brake fluid.

At this point, drain the brake fluid and clean it.

3.Use braking techniques wisely. Mastering braking skills can avoid vehicle vibration and other failures caused by overheating and deformation of brake discs.

Therefore, after braking, the brakes should be released before the vehicle comes to a complete stop, and then gently released until the vehicle comes to a complete stop, so as to avoid huge shocks and shaking when the vehicle stops. Also, when driving on curves, brake before entering a curve to slow down and avoid using the steering wheel brake.

This is the relevant content of the brakes brought to you today, I hope to arouse everyone's attention to the brakes, for everyone's driving safety, we must pay attention to the maintenance of the brakes, to avoid very serious consequences, I believe that we will be able to do safe travel in the future.

I think it's necessary to do it, because it's safer to do it.

It is definitely necessary to do it so that you can get a particularly safe drive while driving, and there will be no brake failures.

It is necessary to do. Regular brake maintenance can ensure that the vehicle will not fail in the process of driving. After all, brake failure can easily be dangerous.

It is necessary. Because braking is very important and related to driving safety, I think it is necessary to do it.

The maintenance time of the brake system is as follows:

1. The front wheel of the disc state posture is about 30,000 kilometers: the disc rear wheel is about 60,000 kilometers: the drum brake is about 100,000 kilometers;

2. The braking system is the key to ensuring safety, and the grip replacement cycle is only a rough reference, focusing on the thickness, and checking in advance is the safest;

3. The brake fluid is replaced at about 60,000 kilometers and Yeqing.
