How many kilometers do brake pads change? How many kilometers do the brake pads change

Hello, the brake pads of the front wheels should last 6-70,000 kilometers. The brake pads on the rear wheels should last more than 100,000 km. Of course, this is not absolute, but only an approximate average.

The front brake pads wear out quickly, because when braking, the center of gravity of the car will lean forward, and the force to be borne by the front brake is greater than that of the rear brake, with a ratio of about 7:3Therefore, the disc heel of the front brake is generally larger than that of the rear brake.

The car is divided into four brake pads, front and rear, and the coaxial ones must be replaced together, so that the braking force on both sides is even. The wear degree and service life of the front and rear brake pads are not the same in many cases, under normal driving conditions, the braking force of the front brake pads will be relatively large, and the degree of wear will be greater, and the service life will be shorter, generally about 3-50,000 kilometers need to be replaced; The rear brake pads bear less braking force, and they can be used longer, generally 6-100,000 kilometers before they need to be replaced.

Under normal driving conditions, the brake pads should be inspected every 5000 kilometers or so, not only to check the remaining thickness, but also to check the wear status of the brake pads, whether the degree of wear on both sides is consistent, whether the return is normal, etc. If an abnormal situation is found, it must be dealt with immediately, and do not wait for the friction material to be partially worn out before replacement, which has a great potential safety hazard. After replacing the new brake pads, it is necessary to run in, about 200 kilometers of running-in, and only after the running-in period can the best braking effect be achieved.

There is no actual kilometer limit to replace, check that the brake pads are too thin to replace, and the replacement is best to replace both sides together, such as the rear side is not good, replace the brake pads of the rear two wheels together.

How many kilometers of brake pads to change, I don't think we need to think about it, because the car needs to be maintained once for 10,000 kilometers, and they will have a record of her, so he will take a look, and if there is a demand, he will remind you to replace it.

It doesn't matter how many kilometers it is, if you drive more steadily and don't drive fast often, it's fine, if you often drive fast, it's more expensive to brake sharply, you can ask them when you maintain it.

Generally speaking, a pair of brake pads is no problem with 100,000 kilometers, and if used well, it can even reach 150,000 kilometers. Since every driver applies the brakes differently, it can be difficult to determine how often the brake pads need to be replaced.

The life of a brake pad is difficult to define in terms of a clear number of kilometers or time.

Brake pads need to be changed in the following situations:

1. Look at the thickness: Usually, the thickness of a new pair of brake pads is about the same, and when the thickness of the brake pads is observed to be less than the naked eye, it is necessary to prepare for replacement. There is also a protruding sign on both sides of each brake pad, the thickness of this sign is about two or three millimeters, which is also the limit of the thinnest brake disc replacement, if the thickness of the brake pad is already parallel to this logo, it must be replaced.

2. Listen to the sound: If the brake is accompanied by the sizzling sound of "iron rubbing iron", the brake pads must be replaced immediately. Because the limit markings on both sides of the brake pads have directly rubbed against the brake disc, it proves that the brake pads have exceeded the limit.

3. Strength: When stepping on the brakes, if you feel very hard, there is always a soft feeling, often need to step on the brakes deeper to achieve the previous braking effect, when taking emergency braking, you will obviously feel that the pedal position is low, then it may be that the brake pads have basically lost friction, and they must be replaced at this time, otherwise it will cause serious accidents.

In general,The life of the brake pads of the front brake is 35,000 km, and the life of the rear brake pads is 6-10w km,Therefore, it is recommended to check the front brake pads every 30,000 km. It depends on the driving conditions of the vehicle and the driving habits of the individual, the key is to see the thickness of the brake pads, if the thickness of the brake pads is less than 3mm, it needs to be replaced.

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.

Precautions after replacing the brake pads.

Changing the brake pads for new ones needs to be broken in. The first is a low-speed run-in, accelerating to 60 km/h, and lightly applying the brakes to a speed of 10-20 km/h. Then the split point brake, when running-in, try to use the split point brake for braking, do not use the emergency brake before the run-in.

It hurts the brakes.

Finally, repeat the above operation. Generally speaking, it takes at least a dozen times, but if you don't have time, you can drive normally. Although this run-in period is long, it is still very safe.

If there are problems such as abnormal noise and shaking of the brakes during the run-in period, it is best to find a repair shop to check it.

01 There is no fixed replacement cycle for brake pads, it is recommended to check them regularly, and generally the brake pads can be replaced at 5-60,000 kilometers.

Brake pads vary according to different driving habits, and there is no fixed replacement cycle. When the brake is about 360,000 kilometers, the brake pads are usually worn out more seriously, the brake pads are about to be worn out, when the brakes are stepped on, the alarm pads on the brake pads rub against the brake disc, and will make a sharp and piercing sound, and many models will also be on the dashboard, prompting brake failure (or checking the brakes, etc.), at this time the brake pads have basically reached the limit state. In daily use, you can also do a simple inspection, most models through the rim, you can see the brake pads on the brake caliper, generally when the brake pads are worn to only about 5mm, you need to consider replacing the brake pads.

In addition, if there is an abnormality in the brakes, it is recommended to check it in time, safety first.

Brake pad self-test method:

1. According to the thickness of the hoof.

Measuring the thickness of the brake pads, the thickness of a new brake pad is approximately and its wear limit is. So when your brake pad thickness is close to or has fallen below, then it must be replaced. Not only that, when the thickness of the brake pad is less than the wear limit, the iron plate on the brake pad will rub against the brake disc to produce metal friction noise, so when the brake is pressed, you can check the brake pad first.

2. Feel the change in braking force.

Another very intuitive way to do this is to feel the change in force when you apply the brakes. If you always feel very hard when you apply the brakes, or feel that the brakes are not as sensitive as before, you need to press harder than you used to to do to get the desired braking effect. When you feel that the pedal position becomes lower and the brake pedal travel becomes longer during emergency braking, then your brake pads must be checked as soon as possible.

3. Observe the fault alarm light.

When the brake pad wear warning light on the dashboard lights up, it means that the brake pad needs to be checked and replaced. However, you need to pay attention to one point, this alarm light is not a brake failure warning light, but a separate fault warning light for brake shoe wear, and this alarm light is not available in all vehicles, so you want to rely on the brake pad wear alarm light to remind yourself to replace the brake pad friends, you must know in advance whether your car has this function. And even if there is this function, when the alarm light is on, it means that the brake pads have reached the wear limit, and this replacement node is still a little late.

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 front brake pads are generally replaced around 3w kilometers.

It depends on the driver's driving habits, the most accurate kilometer and time to replace the brake pad is to check the thickness of the brake pad, if the thickness of the brake pad is less than 3mm, it needs to be replaced.

There are generally 2 types of brakes for the rear wheels, one is disc brake and the other is drum brake. The brake pads of disc brakes are the same as those of the front wheels. Generally, the vehicle needs to be replaced when it travels to about 6w kilometers.

The drum brake generally needs to be replaced when the vehicle travels about 10w kilometers. This number of kilometers is also not absolute, because the driving conditions of each car are different, and the driving habits of each driver are different, which will affect the service life of the brake pads. The number of kilometers that may be used may be long or short.

So the kilometers mentioned above are an approximate value. The most accurate thing is to check the thickness of the brake pads. If the thickness of the brake pad is less than 3mm, it needs to be replaced.

Reminder: It is not recommended to brake sharply often, when encountering a red light, you can release the throttle to slide, reduce the speed of the car by yourself, and it is almost enough to lightly press the brakes when stopping. This can effectively reduce the wear and tear of brake pads.

The replacement time period for brake pads and discs is not fixed, depending on the material of the brake pads, the road conditions of the vehicle, and how often and how hard the driver presses the brake pedal. Generally, the replacement mileage of conventional brake pads is about 10,000-30,000 kilometers per drive.

As a result of friction, the friction blocks are gradually worn out, and generally speaking, the lower the cost of the brake pads, the faster they will wear out. After the friction material is used, the brake pads should be replaced in time, otherwise the steel plate will be in direct contact with the brake disc, and eventually the brake effect will be lost and the brake disc will be damaged.

Brake pads are also called brake pads. In the braking system of the car, the brake pad is the most critical safety part, and the brake pad plays a decisive role in the quality of all brake effects, so a good brake pad is the protector of people and cars.

For general vehicles, under normal driving, the life of the brake pads of the front brake is 3-50,000 kilometers, and the service life of the rear brake pads is 12-150,000 kilometers.

The best time to replace the brake pads, the thickness of the brake pads of the disc brake can be checked by stepping on the brake plate, and the thickness of the brake pads on the brake shoes of the drum brake shoes is to pull the brake shoes out of the brakes. However, whether it is a brake pad on a disc brake or a brake pad on a drum brake, the manufacturer specifies that the thickness must not be less than, because, by all actual measurements, the brake pads wear and peel faster, before or after. Therefore, the owner should check and replace the brake pads on the brakes at or before this time.

Generally, the brake pads of automobiles can be replaced for 5-60,000 kilometers, but they will vary according to different driving habits.

Generally, the mileage replacement cycle of conventional brake pads is 30,000-60,000 kilometers per mileage, which is determined according to the road conditions of the vehicle and the frequency and strength of the driver's brake pedal. In addition, if you feel that the distance of applying the brakes is longer, the sensitivity is not sensitive, or the sound of the brakes is harsher than usual, you need to go to the service station for a check.

What should I do if the steering wheel is locked? How can I avoid this next time?

If you encounter a situation where the steering wheel is locked, it is usually the reason why the deadbolt is stuck. Try turning the steering wheel back and forth, or check if there is a valid key in the car. In order to avoid the situation that the steering wheel is locked, it is recommended to turn the steering wheel back to the front and reverse wheel before getting out of the car, and do not turn the steering wheel when pulling out the key.

Brake pads are generally replaced once every 50,000 kilometers.

Of course, there are about 30,000 kilometers of replacement, and there are about 100,000 kilometers that do not need to be replaced.

Specifically, the mileage of the brake pads is determined by the driving situation and the driving environment, often driving in the downhill or uphill section, you may need to step on the brakes frequently, so the brake pads wear out relatively quickly, if you drive on a flat road, then the brake pads wear out more slowly.

Comparison of old and new brake pads.

Most vehicle brake pads are replaced at about 50,000 kilometers, and brake discs are replaced at about 100,000 kilometers, of course, some cars depend on the situation.

Some vehicles have high horsepower, braking strength, and brake pad wear is also relatively large, so the thickness of the brake pads is also large, it seems that the brake pads of German cars are thicker, and the brake pads of Japanese cars are relatively thin. For example, the brake pads of Mercedes-Benz are basically 12 cm in the front and about 10 cm in the back. And some models of Japanese Infiniti have brake pads in the back centimeters and 10 centimeters in the front.

It's so thin and doesn't change, it's too expensive?

Infiniti Q50L Some vehicles rear brake pads are eccentric, 20,000 kilometers will be replaced, this is a vehicle design problem, the rear brake cylinder needs to be replaced.

The brake pads generally need to be replaced if the wear is less than 3, and if there is enough time, you can also run until the brakes make abnormal noises and then replace them. For example, running to 1 is fine, provided you have enough time to go to the repair shop.

The protruding iron piece is the limit, and it will make an abnormal noise when it is worn to the point that the iron piece is worn.

If you don't have time, it's best to wear it out to less than 3 and replace it. Basically, when it wears out to about two millimeters, the brake pads inside will make an abnormal noise. Because there is a limit iron plate.

Therefore, how many kilometers to change the brake pads depends on the actual situation, regular maintenance and inspection, and the wear is less than 3 can be considered for replacement. If you don't change, you might run 3,000 kilometers.

Some vehicles are equipped with brake sensing cables, and when the brake pads are worn to the point that they need to be replaced, the gauge will light up the replacement brake pads or related fault lights. Therefore, when the vehicle lights up, you can check whether it needs to be replaced.

Car brake pads are not fixed for how many kilometers to replace. It depends on the driving habits and the road conditions that are often walked, as well as the regular load of the vehicle. These have a great impact on the use of car films.

Brake pads are also called brake pads. It is a friction material fixed to a brake disc or brake drum that rotates in conjunction with the wheel. Among them, the friction lining and the lining block bear the pressure from the brake cylinder to produce friction effect, so that the car slows down or stops.

So when exactly will the brake pads be replaced? Due to different driving habits and use conditions, as well as the braking system of each car, there are also differences. Therefore, it depends on the degree of wear of the brake pads.

Generally speaking, brake pads are more than 15 mm thick and have wear signs. If the thickness of the brake pads is less than 10 mm and it is flush with the wear mark. It must be replaced.

If it is not convenient to check it yourself, go to a repair shop with professionals and measuring tools.

The owner can observe the thickness of the brake pads by himself, and there is no need to look at the mileage at all.
