How often does the car change brakes? How often should the brakes be replaced

How often you change your brake pads doesn't really have much to do with time, the main factors are the total mileage you drive, the road you drive, the frequency of braking and the length of braking time. Generally, the brake pads can be replaced after driving about 6 to 7w kilometers in a family vehicle.

So how to know if your car needs to replace the brake pads to make it more economical to repair the car, here are a few examples.

1. If your car has brake pad wear sensing, you can go to the 4S shop to replace the brake pads immediately when the brake wear indicator lights up.

2. If your car is driving normally when the brakes are accompanied by a squeaky sound, you can go to the 4S shop to check and replace the brake pads. This is because some brake pads have a physical wear indicator on them (a steel disc that makes direct contact with the brake disc when it wears to a certain scale, resulting in a squeaky sound).

3. If you often go to the 4S shop for maintenance, check. I believe that the maintenance staff of the 4S shop will notify you as soon as possible (sir, the brake pads of your car should be replaced).

Therefore, how long do the brake pads need to be replaced, the vehicle will generally be fed back to the driver for the first time, and if you are fine, you can often go to the 4S shop to check it, because the inspection is free.

The main wearing parts in the automobile brake system (commonly known as "brake") include: brake pads, power discs, power fluids (brake fluids); Taking family cars (small cars) as an example, brake pads, that is, brake pads, are directly related to the durability of drivers and driving habits; Usually driving habits to use brakes more frequently, the front brake pads use 10,000 kilometers of kilometers. Experienced veteran drivers usually do not use the brakes frequently, and the longest kilometers can reach more than 100,000 kilometers.

The wear and tear of the brake disc is closely related to the driver's habits, according to the wear replacement standard, the brake disc is replaced when the brake pad is replaced a second time (as a rule of thumb). The replacement time of brake fluid (brake fluid) should not exceed two years or 150,000 kilometers, because the boiling point of brake fluid is high; And the characteristics of the brake fluid absorb the water molecules in the air, the water content in the brake fluid can not exceed the standard, such as the water exceeds the standard will make the brake fail, the boiling point of water is very low, easy to produce gas, gas can be compressed, resulting in brake failure!

Change the brake fluid every 40,000 km!

1.Whether the automobile braking system works normally is directly related to the driving safety of the vehicle. Automobile braking systems are generally divided into brake discs, brake pads, brake cylinders, brake oil pipes, ABS control pumps, brake master cylinders and brake oil.

The braking system is related to driving safety, and every maintenance must check for wear and tear.

2.Brake pads are usually replaced every 80,000 km. The wear and tear of brake pads is related to driving habits, vehicle type, vehicle weight, and brake pad material. The friction material of the brake pads is less than 3 mm and needs to be replaced immediately.

3.The general replacement standard for brake discs is that one pair of brake discs corresponds to two pairs of brake pads. "When two pairs of brake pads wear out for the third time, the brake discs should be replaced.

The thickness of the brake disc should be tested and measured every time the brake pads are replaced. The brake disc has a standard stove scale, and the measured value is less than the standard value. Direct replacement of the brake disc.

4.The brake fluid is changed every two years and the driving force is 40,000 km. Brake fluid is hydrophilic.

If the brakes are not changed for a long time, air resistance will be generated, increasing the braking distance. In severe cases, it can cause brake failure. It is recommended to replace the brake hose at the same time as the bending disc or to replace the brake hose directly if the brake hose is broken.

Millions of car purchase subsidies.

Cars are becoming more and more popular, and even during rush hour and statutory holidays, thousands of people will be crowded in the alleys. With a car is convenient to travel, the motor will inevitably wear and tear as soon as it moves, let's talk about how often the car brake pads are replaced.

1. Listen to the sound.

If in the process of daily driving, the brake hears a harsh metal whistling sound, at this time you should pay attention, this is the alarm iron plate on the brake pad has begun to wear out the brake disc, so there will be this kind of sharp metal sound.

Second, two looks. Observe how much the thickness of the brake pads is, if the thickness of the brake pads is less than 3mm, the brake pads must be replaced, because at this time there will be obvious inertia of stepping on the brakes, and you need to step on it very deep to have a braking effect or you need to pedal twice to stop. If it is not very convenient for you, you can ask the master of the 4S shop or auto repair shop to help check it every time you maintain it.

If you are a high-end model, you can see a fault code on the dashboard, and the fault code needs to be replaced immediately, if you do not replace the new brake pads and use professional equipment to eliminate the fault code, the fault light will always be on.

3. Mileage.

Under normal circumstances, after driving 30,000 kilometers of brake pads, every time you go to do maintenance, you need to check whether you can continue to use it, and when you drive to 60,000 kilometers, you obviously feel that the braking effect is not strong, and you need to consider replacing the brake pads at this time.

Fourth, the car feeling. If the brakes feel very hard, it is possible that the brake pads have basically lost friction, and they must be replaced, otherwise it will cause a serious accident.

Tip: This method is relatively abstract and may be a little difficult to grasp based on feelings, so it is important to develop a good self-inspection habit. In addition, the reduction of braking effect will lead to an increase in brake fluid consumption, so it is important to check the condition of brake fluid when replacing brake pads.

Fifth, the brake deviation.

Many friends feel that their vehicles have a slight deviation in driving, and they often determine that they need to do four-wheel alignment. It is important to note that if everything is normal when the vehicle is moving, but it is only mistracking when applying the brakes heavily, it is time to check the braking system.

The methods introduced above can help car owners to carry out daily inspection of brake pads, of course, the naked eye self-inspection is only a rough judgment, the purpose is to detect vehicle problems as early as possible, grasp the current vehicle condition, involving maintenance and replacement and other work, of course, but also rely on professional maintenance stations to carry out.

It is recommended that during daily maintenance, it is best to do 5000 kilometers to check it and prevent it from happening, only in this way can we find and solve the problem well.

The daily maintenance of brake pads still needs to develop a good braking habit, refuse to brake profiteering, braking and sudden braking, and try to predict, brake and brake smoothly in advance, so as to prolong the service life of brake pads and reduce the wear and tear of brake discs.

The car repairer said that the brake pads are generally replaced once when the car travels twenty or thirty thousand kilometers, so remember that twenty or thirty thousand kilometers, as long as it is within this mileage range, to this kilometer, hesitate Everyone has different driving habits, and the frequency of using brakes is different, which also has an impact on the service life of the brake pads.

How often do you change your car? Brake pads. It should need to be opened. About 50,000 kilometers. You can change the brake pads.

There are no hard and fast rules, mainly depending on your use, and the general model has to be about 6 to 100,000.

Under normal circumstances, the life length of brake pads is 2-30,000 kilometers. When it has been 2-30,000 kilometers since you last changed the brake pads, then you may need to go to the repair shop to change the brake pads. Brake pads will become thinner after a long time of use, when braking, you will feel that you can't use the force, and it will make a sound like a snake spitting out a letter, this situation must not be delayed, go to the maintenance plant as soon as possible to replace the new brake pads, otherwise you will be lucky on the road, and the possibility of accidents is relatively large.

It is important to check the wear and tear of vehicle parts on a regular basis, but it is not necessary to replace it when the regular service life expires, because each car owner has a different way of driving and the degree of wear and tear of parts is also different. Some car owners may drive more gently, and the maintenance is also better, so the service life of vehicle parts will be extended, for example, the regular life of brake pads is 2-30,000 kilometers, but the maintenance can be used for 4-50,000 kilometers. In this case, the brake pads may be scrapped after less than 2-30,000 kilometers and need to be replaced in advance.

In general, the front brake pads are replaced about 30,000 kilometers, and the rear brake pads are replaced about 80,000 kilometers, of course, this is only an approximate direction, according to each person's different car habits, and the braking system of each car is also different, so the replacement time should be determined according to the degree of wear, but it is best not to exceed this number.

There is a driving official account.

The brake pad replacement cycle of the car: the front brake pad is about 30,000 kilometers to replace, and the rear brake pad is about 80,000 kilometers to replace, which is only an approximate time, according to the different habits of each person and the different braking systems of each car, the replacement time should be determined according to the degree of wear, but it is recommended not to exceed this number.

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.

After the brake pads are worn to a certain extent, the braking force of the vehicle decreases, which seriously affects our daily driving safety, so it must be replaced immediately, and most owners replace the brake pads at 4-50,000 kilometers.

However, depending on the driving habits, the replacement time will vary, so the replacement time is not fixed and needs to be checked regularly. At the same time, there is also a difference between the replacement time of the front brake pad and the rear brake pad, the service life of the front brake pad is 30,000 kilometers, and the service life of the rear brake pad is 60,000 kilometers.

Look at the degree of wear of the brake pads, there will be grooves on the brake pads, when the wear to the plane and the groove is at the same level, it means that the groove is gone, and the brake pads should be replaced in time.

Inspect the vehicle

The steel plate should be coated with socks to prevent rust, the thermal insulation layer is composed of materials that do not transfer heat, the purpose is heat insulation, when braking, the friction block is squeezed on the brake disc or brake drum to produce friction, so as to achieve the purpose of vehicle deceleration and braking, over time, the friction block will gradually be worn out. The end of the year.

Some models have induction wires on the brake pads, when the brake pads are worn to a certain extent, the alarm light will appear on the dashboard, which means that the brake pads need to be replaced in time, otherwise the alarm light will always be on. While driving, when you tap the brakes, if you hear the sound of squeaking metal rubbing. It is usually caused by the brake pads exceeding the use limit, so it is necessary to check in time and replace the brake pads once there is an abnormality.

There may be some controversy about the replacement cycle of brake pads, mainly because the owners of the repair shop want to extend the replacement cycle, and the repair shop wants to shorten the replacement cycle.

Perhaps most car owners have encountered this situation with large bands. The owner goes to the repair shop of the 4S shop for maintenance. The people in the shop only look at the mileage of your car and immediately recommend that you replace the brake pads.

Generally, the owner of the car who does not know it can be replaced directly. In fact, many times the brake pads do not need to be replaced. Whether the brake pads need to be replaced or not is not only related to the mileage, but also to the actual thickness of the brake pads.

When do brake pads need to be replaced?

In daily use, the owner pays more attention to the thickness of the brake pads, and the brake pads need to be replaced when they are worn to 3 mm after visual inspection. If the owner does not have the habit of checking the vehicle, there is no problem, because there are alarm sensors on the brake pads. When the brake pads are too thin, the brake pad sensor will sound an alarm on the dashboard.

After the owner confirms that the brake pad is alarmed, don't panic too much and drive to the 4S shop to replace it.

Summary: Driving habits have a great impact on the use of car brake pads, and the driver always steps on the brakes during the car driving, which not only consumes fuel but also wears the brake pads, especially when encountering traffic jams, the loss of brake pads is greater. One thing to note::

The brake front pad (front model) of many models needs to be replaced at 28,000 kilometers, but someone can drive the same car to 35,000 kilometers, because of driving habits.

<> "How often should the brake pads be replaced.

As we all know, cars need proper maintenance, and if not properly maintained, there may be safety hazards. Generally speaking, a relatively new car does not need to be over-maintained, but a car that has been driven for two or three years or has been driven for thousands of kilometers needs to be replaced regularly to avoid affecting the performance of the vehicle.

So in addition to common engine oil, what parts need to be replaced? How often do you replace them?

The first is the filter element, which is often referred to as an air filter, gasoline filter and oil filter, which need to be replaced frequently. Among them, the replacement time of air filter is 10,000 kilometers, the replacement time of gasoline filter is 20,000 kilometers, and the replacement time of oil filter is 5,000 kilometers. These filters can be very useful, but they can also easily fail, so they should be replaced promptly.

The second is the spark plug, which is a very important and easily damaged part of the car, if there is no habit of replacing the spark plug, the harm is very large, which will not only lead to the difficulty of ignition of the car, but also lead to insufficient power of the car and accelerate the formation of carbon deposits.

In addition, it should be noted that the replacement time of the spark plug has a lot to do with its material. If it is an ordinary nickel alloy spark plug, then it is enough to replace the spring branch every 2-30,000 kilometers. If it is a platinum spark plug, it is enough to replace it every 60,000 km.

If it is an iridium spark plug, it will be fine to replace it every 80,000 km.

Finally, there are the brake pads that are about safety. As we all know, brake failure is bad, and brake pads are one of the most critical safety parts in a car's braking system. Generally, car brake pads need to be replaced every 3-50,000 kilometers.

In addition, it should be noted that when the brake warning light on the dashboard is on, everyone must replace the brake pads immediately; When the thickness of the brake pads is less than 3mm, the brake pads should be replaced immediately. The replacement of brake pads must not be delayed, which will affect driving safety.
