How long do brake pads last??? How long do car brake pads generally last

Not necessarily! Varies from car to car and from person to person.

Walking conditions First of all, the street is the main occasion. But the conditions of highways, hillside roads, and country roads are different.

In fact, the biggest influencing factor is temperature.

The reasons for the change in temperature are:

The weight of the car, the ventilation effect of the car's braking, and the frequency of the driver's braking.

In addition to the driver's driving habits (how much the brakes use), the factors that can change the temperature of the brakes affect the service life of the brake pads.

Heavy car brake pads are used fast, MPV, etc.

Brake pads for sporty cars are fast, and brake pads for automatic light cars are slow.

Is it polished and replaced? No!

The sooner you replace it, the better. 30,000 kilometers for small cars, 20,000 kilometers for sporty cars, 10,000 kilometers for heavy cars.

Why? The thinner the thickness of the brake pads, the faster the wear will be, and when the thickness is not enough, the heat insulation effect will be low, and the rise in temperature will accelerate the wear. Moreover, the temperature of the brake disc is above 350 degrees, and it is difficult for ordinary brake pads to maintain the normal friction effect.

When the brake pads are halfway grinded, many people think that they can walk the same distance as they have so far, which is a wrong idea. The remaining half of a normal brake pad grinds twice as fast.

The thickness of a new brake pad is generally around the limit, and the thickness will gradually become thinner as the friction continues to be used in use. Professional technicians suggest that when the thickness of the brake pads is observed by the naked eye, there is only 1 3 thickness left (about about 1 3 thickness, the owner should increase the frequency of self-inspection, ready to replace at any time.

As a qualified driver, you should have a good grasp of the state of the whole car during the driving of the car, especially the brake system of the car, such as the brakes of the car become soft and hard. When it comes to the brake system, I have to talk about the brake pads of the car, because the brake pads not only affect the braking performance of the car, but also a part that is easier for the owner to check and has a long maintenance cycle. But many car owners still have doubts, what is the replacement cycle of brake pads, and when should the brake pads be replaced?

Composition of brake pads.

Brake pads are composed of friction material layer, heat insulation layer, adhesive layer, back plate, etc. The brake pads push the back plate through the brake cylinder to press the friction material of the brake pads on the brake disc for braking, so the quality of the friction pads is particularly important. Some brake pad friction pad material is harder, the braking effect is poor but the service life is long, and some brake pad friction material is softer but the braking performance is good, from this point it can be seen that the life of the brake pad is directly related to the quality of the friction material.

Brake pad replacement intervals.

Car owners may have 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, the car owner went to the 4S shop repair shop for maintenance, and the people in the shop only looked at the mileage of your car, and immediately recommended you to change the brake pads ......In fact, there are many times when the brake pads do not need to be replaced, whether the brake pads need to be replaced is not only related to the mileage, but also depends on the actual thickness of the brake pads.

When do brake pads need to be replaced?

In daily use, the owner should pay more attention to the thickness of the brake pads, and when the brake pads are worn to 3mm visually, they need to be replaced. If the owner does not have the habit of checking the vehicle, there is no problem, because there is an alarm sensor on the brake pads, when the brake pads are too thin, the brake pad sensor will alarm on the dashboard, the owner confirms that the brake pads are alarmed, do not 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 front brake 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.

The maintenance and replacement of brake pads, people often ask, how often the brake pads are replaced is the most appropriate, this is a difficult question to answer, in addition to often running long distances to save brakes, the most important thing is whether the driving style is appropriate, in general. A pair of brake pads is no problem with 100,000 kilometers, and if used well, it can even reach 150,000 kilometers. When exactly to return the brake pads, you have to decide by yourself, below I will share a few tips, if you need to take a look.

Tip 1, how to check the wear and tear of the brake pads and how to replace them.

1. Under normal driving conditions, check the brake shoes every 5000 kilometers, not only to check the remaining thickness, but also to check the state of the wear of the shoes, whether the degree of wear on both sides is the same, whether the return is free, etc., and the abnormal situation must be dealt with immediately.

2. The brake shoe is generally composed of two parts: iron lining and friction material, and the shoe must not be replaced only after the friction material part is worn out.

3. When replacing, the brake pads provided by the original spare parts should be replaced, only this can make the braking effect between the brake pads and the brake disc the best and the least wear.

4. After the replacement, be sure to step on the brake a few times to eliminate the gap between the shoe and the brake disc, resulting in the first foot without braking, which is prone to accidents.

5. After the brake shoe is replaced, it needs to be run in for 200 kilometers to achieve the best braking effect, and the shoe pad must be driven cautiously.

Tip 2: Look at what you need to look out for.

1. The material and structure of inferior brake discs or drums are easy to cause early wear of brake pads.

2. Due to the long-term use of the brake caliper of the braking system, the brake does not return, which makes the disc and disc (drum) drag and grind for a long time, resulting in abnormal and serious wear.

3. The materials used in the brake pads do not meet the requirements and the design density of the friction layer of the brake pads is unreasonable (small), which is also one of the reasons for the serious wear of the brake pads.

4. The design area of the brake pads of the original car is small, and it is also the main reason for the serious wear of the brake pads in long-term speeding, frequent braking, overload work and long-term high temperature.

So how can you tell if you need to replace it?

Because the brake pad is a component related to driving safety, if it is not replaced, it is easy to directly damage the brake disc, and the safety factor is reduced, affecting life safety, so how to judge that the brake pad needs to be replaced? Generally, the front wheel brake pad is less than three millimeters, and the rear wheel brake pad is less than two millimeters must be replaced, under normal circumstances, even if the thickness of the brake pad is greater than the above standard, the brake pad must be replaced every 40,000 kilometers. Moreover, if you use the original parts, if you use the analogue, it is easy to damage the brake disc, and the cost of replacing the brake disc is much higher, which can be said to be more than worth the loss.

Hello, there is no fixed replacement time for the brake pads of this car, and there are kilometers, generally 60,000 kilometers, which need to be checked.

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.

The brake pads need to be changed once every 3 to 6 km. 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.

How often should brake pads be changed? The professional technician gave advice, novices should not be careless, it is too dangerous.

The replacement time interval for brake pads and discs is not fixed, depending on the road the vehicle is driving and how often and how hard the driver presses the brake pedal. Under normal driving, the life of the front brake pads is 2-4w km, and the life of the rear brake pads is 6-10w km, so it is recommended to check the front brake pads every 30,000 km. The thickness of the new brake pad is generally about that, with the daily friction loss, when the naked eye observes that the thickness of the brake pad is only 1 3 brand new, it is necessary to increase the frequency of inspection, and be ready to replace the new brake pad at any time.

There will be small raised signs on both sides of the brake pads, and when the brake pads are level with it (2-3mm), it means that it has reached the limit and must be replaced.

There is no fixed saying that the brake pads are changed how often, it depends on the driving road conditions and driving habits, these habits will affect the use of brake pads, and a pair of brake pads can reach 100,000 kilometers if they are used well.

1. Check the thickness.

Generally, the thickness of new brake pads is about , and it will be constantly thinner by friction during use. If you can see that the black friction material of the brake pads is almost worn out, and only one-third of the thickness (about 5 mm) remains, it is time to consider replacing it.

2. Listen to the sound.

If you hear it when you tap the brakes"Sizzle" sound, similar to the sound of iron rubbing iron, at this time it is necessary to replace the brake pads in time. Because the brake pads are too thin, the limit markings on both sides have directly rubbed against the brake discs.

3. Brake pad wear warning light.

Some high-end models are also equipped with brake pad wear warning lights, which can be judged according to whether the brake pads need to be replaced according to the light or not. Generally, the warning light is on to indicate that it is close to the limit and needs to be replaced in time.

4. Rely on the car feeling.

If you feel a little strained when you apply the brakes, there is always a soft feeling, and you need to press the brakes very deeply to achieve the previous braking effect. At this time, the friction of the brake pads may be basically lost, and it must be replaced, otherwise it is easy to cause traffic accidents.

1. Brake pads have a great impact on the braking performance and safety performance of the car, generally speaking, the life of a pair of brake pads is between 10,000 kilometers and 60,000 kilometers, and the degree of wear and tear is different according to the driving habits of each high-impact nuclear person, of course, it is related to the driving environment, the weight of the car, and so on.

2. However, the replacement cycle of brake pads is long, and for friends who do not use cars frequently, it may take more than a year for brake pads to be replaced.

3. Brake pads and brake performance are closely related, so stepping on the brakes can naturally feel a certain difference, if the brake pads are on the edge of the need to be replaced, then the brakes will become weak as a whole", that is, the car has a feeling of not being able to brake, in this case, it is necessary to consider checking and replacing the brake pads.

Between 30,000 and 50,000 km, the brake pads are replaced. If the application of the car hall pin exceeds 30,000 kilometers, the brake pads should be checked regularly, the specific thickness of the brake pads should be checked, and the brake pads should be replaced immediately when they cannot be used to ensure safety. Brake pads must be replaced in the following cases:

1。Look at the thickness: In general, the thickness of the new brake pads is around the same.

When the thickness of the brake pad is less than centimeter, it needs to be replaced. There is also a raised markings on the sides of each brake pad. The thickness of this mark is about two or three millimeters, which is also the limit value for the thinnest brake disc replacement.

If the thickness of the brake pads is now parallel to that of the label, they must be replaced. 2.Listen to the sound:

If you gently apply the brakes with the hissing sound of "iron against iron", the brake pads must be replaced immediately. Since the limit marks on both sides of the pads are now rubbing against the brake discs, it is confirmed that the brake pads are now past the limit values. 3.

Sense of power: When you apply the brakes, if it feels very hard, there will always be a soft feeling. Usually, you have to apply the brakes deeper to achieve the previous braking effect.

When applying emergency braking, you will feel that the pedal position is noticeably lower. Then it may be that the brake pads are basically no longer frictional, and they must be replaced at this time, otherwise it will cause serious safety accidents. Millions of car purchase subsidies.
