How often do brake discs need to be replaced

Generally, the brake pads need to be replaced after 3-40,000 kilometers, and the brake disc needs to be replaced when it is left to 70,000 kilometers, and the use time of the brake pad is relatively short, and the brake disc of the car will be replaced after being replaced twice, and the rear brake will be replaced for 8-100,000 kilometers.

In fact, there are two data on the brake disc, one is the thickness of the new disc, and the other is the thickness of the limit after use, if it is lower than that limit data, it must be replaced. Personally, I think that due to the different driving habits of everyone, the different brake discs and brake pads used, the European standard is to wear 2 mm or 5-60,000 kilometers and need to be replaced, and there are deformed brake discs, while in China, there are no hard and fast rules. In fact, brake discs and brake pads are an important work that must be checked before driving, and some 4S shops are indeed very responsible and can remind you that the brake discs need to be replaced.

If the brake is tapped, accompanied by the slightest sound or shouting (it may also be the effect of the brake pads running in at the beginning of installation), 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. In this case, when replacing the brake pads, it is necessary to cooperate with the inspection of the brake disc, when this sound occurs, the brake disc has been damaged, scratches, even if the new brake pads are replaced, the sound can not be eliminated, it is recommended to replace the brake disc in time.

In addition, some bad quality brake pads have hard spots, which will also produce abnormal noise, and in general, the abnormal noise generated by this will disappear after a period of grinding.

Although there is a theory that it is said that the frequency of "two sets of brake pads and one set of brake discs" should be done, the actual situation is far beyond this period, and it is common for brake discs to be replaced for more than 100,000 kilometers. Because the brake system is different from other systems, it mainly depends on the frequency of personal use and driving habits, and drivers who often accelerate sharply and step on the brakes sharply must wear out the brake pads and brake discs more seriously. Most brake disc products have a wear indicator, which means that there are 3 small dimples on the disc surface.

Use a vernier caliper to measure the depth of the pit. In other words, the total wear depth of the brake disc on both sides reaches 3mm, and it needs to be replaced. Generally, the brake pads need to be replaced after 3-40,000 kilometers, and the brake discs need to be checked to see if they need to be replaced after 70,000 kilometers.

This should be determined according to the actual situation, simply use the mileage as a change index is not scientific, it depends on the driver's driving habits, load capacity, etc., the wear and tear of the car killing disc of the brakes should be faster, and the habit of stepping on the brakes early can well protect the killing disc, and also save fuel. My car has been used for more than ten years, with a mileage of 150,000 kilometers, and I have only replaced the front kill pads once, and the brake disc is slightly worn, and the repair technician said that it is no problem to run another 150,000 yuan.

Hello subject! It depends on the condition of the car, generally speaking, the vehicle has to change the brake disc after driving about 100,000 kilometers, it depends on the situation, sometimes the driving environment is very bad will accelerate the damage of the brake disc.

I didn't say how often I changed it, depending on my driving habits, in my group of car friends, some of them change once a year, and my own car only changes once a year when I drive less; If you usually like to brake suddenly, the brake disc will wear out badly, and the frequency of replacement will be high. The principle is to replace the safety line when it is worn to the point and there is abnormal wear.

Because the brake disc and the brake pad are in direct contact with friction, therefore, the material of the brake pad is quite important, many friends have replaced the inferior brake pad, the material is too hard, and the brake pad has hard impurities, then it may cause excessive wear and tear of the brake disc, the specific performance is that there is a ring wear dent in a certain part, which shows that your brake pad is too hard, resulting in abnormal wear and tear of the brake disc, at this time, the disc machine needs to be processed by the disc machine, but the disc of the disc machine is actually the uneven convex part of the brake pad is ground flat. This results in thinner brake discs. Sometimes after intense driving in a high temperature environment, the brake disc is in a hurry to wash the car in a high temperature state, and because the material of the brake disc is cast iron, it is easy to deform when it encounters water at high temperature, and once the brake disc is deformed, it can only be replaced.

This thing looks at the car, the person, and the road conditions, and it is nonsense to say that tens of thousands of things need to be replaced, and there is no quantitative concept of kilometers. It depends on the degree of recessing of the disc Under normal circumstances, under the premise that there is no abnormal fault, every time the brake pad is replaced, the brake disc is replaced, that is, the disc is twice the life of the plate. If your car is about to be sold or is going to be scrapped, it is no big deal if you don't change it and continue to use it for 10,000 or 20,000 kilometers.

If there is no other damage, it generally depends on the wear of the brake disc.

The use cycle of the brake disc is related to driving habits, the use of the environment, and the quality of the brake pads, there is no way to fix the use cycle, my friends, some people 20,000 times, they changed the brake disc, my car is 110,000 kilometers, there is no sign of replacing the brake disc.

This depends on driving habits, and those who drive a private car need to change it for a long time. If you drive a bus, you have to look at the diligence point, and the brake pads are damaged by one foot of the accelerator and one foot of the brake, especially when driving a special car.

A: The brake disc is replaced once every 150,000 kilometers.

It has a lot to do with the brand and driving habits, my current brake pads are almost 100,000 kilometers, the brake pads alarm scale is normal, not to mention the replacement of the brake disc, it is estimated that it is related to running at high speed.

Cadillac XTS has not changed brake pads and brake discs for 280,000 kilometers, and the maintenance inspection is still within the safe use range.

1.Under normal circumstances, the brake disc needs to be replaced every 5 to 80,000 kilometers, and the replacement cycle of the brake disc is related to the individual's driving habits and driving conditions. The brake disc is a wearing part in the braking system, and as the mileage of the car increases, the brake disc will continue to wear out, and after the brake disc is worn to a certain extent, it needs to be replaced.

2.The braking system is very important for the car, and the braking system is related to the driving stability and driving safety of the car. The main components of the brake system include brake discs, brake pads, vacuum booster pumps, brake master cylinders, and brake sub-cylinders.

The vacuum-booster pump provides assistance, and after the driver presses the brake pedal, the vacuum-booster pump can provide assistance, so that the driver can easily press the brake pedal. When the brake pedal is pressed, the brake master cylinder pushes the brake cylinder through the brake fluid, and the brake cylinder pushes the brake pads to clamp the brake disc so that the car can slow down.

3.The brake fluid in the braking system needs to be replaced regularly, and if the brake fluid is not replaced for a long time, it will lead to a decrease in braking force and a longer braking distance. Brake fluid is a fluid that absorbs water easily, and when the water content of the brake fluid reaches 3%, it should be replaced.

When changing the brake fluid, the air in the braking system lines should be emptied, otherwise the braking force will also be affected.

How often the brake disc is changed depends mainly on the road conditions of the car, the frequency of use of the car and the habits of using the car, rather than on the time of day. Generally, the brake pads need to be replaced about 3-40,000 kilometers, and the brake discs need to be replaced about 70,000 kilometers.

Hello, about 80000 kilometers can be checked and replaced.

It is more appropriate to change the brake disc for about 70,000 kilometers.

Brake disc: A brake disc is a disc that also rotates while the car is moving. The brake caliper clamps the brake disc and generates braking force. When braking, it clamps the brake disc to reduce the hand speed or stop with a stupid chain. Brake discs brake well and are easier to maintain than drum brakes.

Service life of brake discs:

The service life of brake pads is generally 30,000 to 40,000 kilometers, and the service life of brake discs is generally about 70,000 kilometers. Generally speaking, after replacing the brake pads twice, it is time to replace the brake disc with potatoes. When braking, I heard a screeching metallic creak.

This is the alarm iron on the brake pads that has begun to wear down the brake discs. Also, most brake disc products have a wear indicator with three small pits on the disc surface. The depth of the pits measured with vernier calipers is 3 mm in total wear on both sides of the brake disc, and it is recommended to replace the brake disc in time.

Millions of car purchase subsidies.

We all know that the engine of a car is very important, but in addition to the engine, other components such as transmission, transmission and spare shaft, braking system, etc. are also important. In the braking system, the brake is quite critical, and once the brake goes wrong, it is very dangerous. Do you know how often the brake discs are changed?

How often should the brake discs be replaced.

Generally speaking, the brake pads and brake discs used in the disc brake system are: 3-40,000 kilometers of brake pads, 6-70,000 kilometers of brake discs - that is, the brake pads should be replaced twice. The rear drum brake is basically 8-100,000 kilometers a change.

The above data mainly depends on the specific wear and tear of each part, and also varies from person to person, but it is not recommended to replace it when it is almost worn out.

It is not necessary to change the brake pads to change the brake disc, if the brake pads are still very thick, you can replace the brake disc without changing the brake pads. In fact, it also depends on the situation, generally speaking, it takes two brake pads to replace the brake disc once. When it is found that the groove depth on both sides of the brake disc adds up to more than 3 mm or the edge of the brake disc becomes sharp, it needs to be replaced in time.

Brake pads are a very important maintenance for driving safety, to have a sense of regular inspection, during routine inspections, to see the degree of wear and tear of the brake pads, if it reaches a critical point, it needs to be replaced immediately. Otherwise, the brake fails, the owner's life is very dangerous, some cars of Gao Shikai will be equipped with a brake pad cavity back-destruction warning light, which will remind the replacement of brake pads, which also saves the owner from worrying and paying attention to the brake pads all day long.
