After driving the vehicle for a long time, how to judge whether the brake disc should be replaced?

If you want to change the brake disc after driving for a long time, you can choose to go to the 4S shop to ask. Some cars will install alarm indicators, if the instrument panel on the model is no longer displayed, it means that it is to be replaced. If the brake disc is worn or malfunctioned for a long time, the light will always be lit.

Be sure to check and replace the brake disc in time, so that you can find the problem of the car in time. If the brakes suddenly fail on the highway, the threat to people is very great, and it is easy to lose your life. <>

If you don't know whether to replace it, you can choose to look at the thickness of the brake disc, whether there is that kind of concave and convex type. If you find that the concave and convex type of the brake disc no longer exists, it means that the brake disc has been seriously damaged, and it must be replaced in time to avoid a strange noise in the car. When replacing, you should also follow the indicator light, and you must check it regularly after understanding it clearly, so as to develop a good habit.

The car needs to be maintained in the process of use, so as to improve the experience of the car. <>

If you don't know whether to replace the brake disc or not, you have to leave it to a professional. The new brake discs are smoother and will be very wear-resistant. In the process of using the car, you will encounter some problems, and you should also make yourself lighter when braking.

When these professionals repair the car, they should also ask them what the condition of the car is like in time, and do not wait until the car is used to the limit before repairing. Usually when you go out, you must do a routine inspection of the car to see how the parts of the car are and how thick the brake pads are. If some equipment is aging and not replaced in time, it may bring a warning to yourself.

Every part has its final limit, so be sure to touch it with your hands at this time and let the professionals talk about it. <>

After driving the car for a long time, when the emergency brake is made, the car feels that the response of the car is relatively slow, or when the brakes are stepped on in a rainy day, there will be a sizzling sound, so you should go to the 4S shop in time to change the brake pads.

It is necessary to look at the alarm indicator, to see the abnormal brake noise, to see the thickness of the brake disc, and to replace it if there is an abnormality to avoid it.

If it has been driven for more than half a year, the brake disc should be replaced, because it must have been worn to a certain extent, and there is always no harm in replacing it.

You can listen to the sound of the brakes, if the sound is particularly heavy, it should be replaced, if it is not heavy, it should not be replaced.

How to determine whether the brake disc should be replaced:1. The frequency of brake disc replacement is high, and the thickness of the brake disc needs to be checked more; 2. Wear and tear**, in addition to the normal wear and tear of the brake disc, the quality of the brake pad and the wear caused by foreign objects during normal use; 3.

If the brake disc is worn by a foreign object, there will be a deviation in the deep groove or the wear on the surface of the brake disc. If there are thin places and thick places, it is recommended to replace them; 4.The normal new brake disc friction pads are 1cm to thick, and only need to be replaced by 3mm to 5mm; 4.

When you step on the brake lightly, you hear a sharp metal friction sound, the thickness of the brake pad is close to the use limit, and the metal disc on both sides of the brake pad is warning that the metal disc has rubbed against the brake disc and needs to be replaced; 5.After the brake pads are polished, the exposed metal parts of the brake pads rub directly against the brake disc, leaving grooves on the brake disc, and the brake pads need to be replaced and the brake disc re-polished.

When the owner uses the vehicle, it is necessary to regularly maintain and replace the parts of the vehicle, especially the brake disc of the vehicle, which can make the vehicle brake normally, so how to judge that the brake disc should be replaced.

1. Whether the brake disc needs to be replaced can be judged by the thickness of the brake disc, under normal circumstances, the thickness of the brake disc of the vehicle is about centimeter, when the brake disc is worn to one-third, or less than 5 mm, it is recommended to replace the brake disc.

2. You can also replace the brake disc of the vehicle in a timely manner through the prompts of the vehicle, and some vehicles with higher configurations will be equipped with brake disc sensors, and after the brake disc is worn to a certain extent, it will directly remind the car to replace the brake disc.

3. If the brake disc of the vehicle needs to be replaced, when the driver steps on the brake, the brake disc will have a serious metal friction sound, and the owner can also judge whether the brake disc needs to be replaced according to the sound.

4. If the vehicle cannot be braked, or the brakes are struggling, the owner needs to check the use of the brake disc in time, which may be that the vehicle needs to replace the brake disc.

5. The groove is too deep;

6. Abnormal brake noise;

7. a brake disc is deformed;

4. Replacement cycle. The brake axle disc is a round plate, which rotates with the vehicle when driving, and acts together with the brake caliper and brake pads, and when the brake is stepped on, the brake caliper and brake pads clamp the brake disc to slow down or stop.

The types of brake discs are: 1. Solid brake discs;

2. Ordinary ventilated brake discs;

3. a perforated brake disc;

4. a scribing brake disc;

5. Ceramic composite brake disc.

The precautions for buying brake discs are:

1. Check the integrity of the product packaging;

2. Whether the anti-counterfeiting mark and packaging logo are consistent with the logo on the brake disc;

3. Whether the product model is consistent with the content of the certificate.

Braking is an indispensable device system for autonomous driving, motorcycles or automobiles. The brake disc is a very important component in the braking system, and the braking system achieves braking by holding the brake disc with a caliper. Brake discs wear out after long hours of work, but worn parts should be replaced regularly.

Failure to replace it can have serious consequences, such as a broken brake disc. Let's take a look at how many kilometers of brake discs this Bianxiao station car has changed.

Introduction to Brake Disc Replacement: How often should the brake disc be replaced?

Brake disc replacement cycle: Most brake discs need to be replaced after 3-40,000 kilometers and 70,000 kilometers. The use time of the brake disc is relatively short, most of them start to replace the brake disc of the car after two replacements, and the rear brake needs to be replaced after 8-100,000 kilometers.

I think how long a car's brake disc can last depends on the road conditions you drive, how often you use the car, and how you use the car. So no one can say exactly how many years it will take to replace it, because everyone is basically different.

Introduction to Brake Disc Replacement: How to Judge?

1.Look at the frequency of brake pad replacement.

If the brake pads are replaced frequently, the thickness of the brake disc needs to be checked frequently. Because the use of brake discs and brake pads wears out year by year, it is necessary to maintain the brake discs regularly.

2.Judging by the wear and tear.

In addition to the normal wear and tear of the brake discs, there are also the development and variation of the quality of the brake pads and brake discs, as well as the wear caused by foreign objects during use. If there is a deep groove in the place where the foreign body is worn, or there is an error in the surface wear, it is recommended to replace it, because this wear will affect our driving safety at the same time.

3.The little partner can follow the necessary rules to consider the replacement.

For example, the brake disc is replaced every two brake pads.

4.The service life of the brake disc is determined by the quality of the brake disc itself and the personal driving habits of the partner.

In most cases, the service life of the brake disc should exceed 100,000 km.

5: Check the wear of the brake disc.

Check whether there is a deep groove of more than 1 mm on the brake disc, whether the thickness of both sides of the brake disc is consistent, whether the brake disc is uneven or cracked, etc. If you have the above problems, replace the brake disc immediately.
