The new brake pads only have the friction of the outer ring, is it normal?

How to maintain car brake pads.

Brake shoes, commonly known as brake pads, are consumables, which will gradually wear out in use, and must be replaced when worn to the limit position, otherwise it will reduce the effect of braking and even cause safety accidents.

Brake shoes are life-threatening and must be treated with care.

Most cars use the front disc rear drum brake structure, under normal circumstances, the front brake shoe wears relatively quickly, and the rear brake shoe is used for a relatively long time, and the following aspects should be paid attention to in the daily inspection and maintenance:

1.Under normal driving conditions, every 5000 kilometers of the brake shoe is inspected, not only to check the remaining thickness, but also to check the state of the shoe wear, 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.Brake shoes are generally composed of two parts: iron lining plate and friction material, and you must not wait for the friction material part to wear out before replacing the shoes. For example, the front brake shoes of the Jetta have a thickness of 14 mm, while the limit thickness of the replacement is 7 mm, including more than 3 mm of iron lining and nearly 4 mm of friction material.

Some vehicles have a brake shoe alarm function, once the wear limit is reached, the instrument will alarm to prompt the shoe to be replaced. The shoes that have reached the limit of use must be replaced, even if they can be used for a period of time, it will reduce the effect of braking and affect the safety of driving.

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

4.When replacing the shoes, a special tool must be used to push the brake cylinder back. It cannot be hard pressed back with other crowbars, which can easily cause the brake caliper guide screw to bend and make the brake pads stuck.

5.After replacing the shoe, 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.

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

Normal, the new disc and brake disc are not in the way.

The brake system of the car needs to be replaced regularly, and some parts next to it are polished before replacing the brake pads. This is for the brake pads to be stronger.

Because on the new brake pads, there is a protective film formed by oxidation, and if this oxide film is not removed by sanding, the brake pads will be worn out. As a result, the life of the brake pads becomes shorter.

If it is installed directly, the edge will be in full contact with the brake disc, and the noise will be louder, and the friction will be measured to make it more solid.

If the thickness of the brake pads is less than 5 mm, they need to be replaced in time.

The thickness of the new brake pads is around centimeters, and the thickness will be reduced by friction as the car brakes during use. Generally, the critical point of the thickness of the brake pad is about two or three millimeters, and if the thickness of the brake pad is less than 5 millimeters, it needs to be replaced in time. If you feel that the brake pedal is light or the brake is hard, it also indicates that the thickness of the brake pad is not enough, and it needs to be checked and replaced in time.

The quality of the brake pad affects the braking effect of the car, which is a very important component for the car and the guarantee of personal safety. Brake pads belong to consumables, in the process of daily driving, often need to brake, brake wear will reduce the thickness of the brake pads, the thickness of the brake pads has a great impact on the braking effect, the thinner the brake pads, the worse the braking effect, the longer the braking distance, and the more can not brake the car. So it needs to be replaced regularly.

Brake pads are generally checked every 3,000 kilometers, and need to be replaced once after 3-40,000 kilometers, but the specific use should be decided according to the actual use and personal driving habits. To develop the habit of regular inspection, for the new brake pads, it needs to go through a certain run-in period in order to effectively maximize its braking effect.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Questions. What about people?

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! According to the extent to which your brake disc is worn and needs to be replaced, the following reasons need to be replaced: First, the brake disc has been worn to the limit, and the wear position!

Second, the brake disc is pulled and there is a big scar, and the groove needs to be replaced. Third, the brake disc is in use. For example, when the steering wheel shakes when the brakes are pressed, the brake disc needs to be replaced!

Warm reminder that your car is maintained on time, change the oil every 5000 kilometers, usually refuel to the regular gas station to refuel, such as Sinopec or PetroChina gas station refueling, so that the quality of the oil is guaranteed, can reduce the engine carbon deposit, reduce engine wear and extend the service life of the engine, I hope my answer can help you!

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.

Summary. Hello, dear, the brake disc is worn out and replaced with new brake pads useful. The brake pads themselves are wearing parts, but when we check and replace the brake pads, we should also pay attention to the condition of the surface of the brake disc, if there are relatively clear scratches, it is recommended to replace the brake disc with a new one, so as to avoid unexpected consequences.

After pulling the handbrake for a minute, release the footbrake, and then release the handbrake after dozens of seconds, and you're done! This means emptying the air from the brake tank.

Hello, dear, the brake disc is worn out and replaced with new brake pads useful. The brake pad itself is a wearing part, but at the same time as we check and replace the brake pad, we should also pay attention to the condition of the surface of the Tongyi brake disc. After pulling the handbrake for a minute, release the foot on the congratulatory brake, and release the handbrake after dozens of seconds, and you're done!

This means emptying the air from the brake tank.

After the operation, you just feel that the brakes are the same as the new car you bought. If it still doesn't work, generally speaking, the brake fluid has moisture, just change the bottle. The brake fluid is generally changed once at 30,000-50,000 kilometers, and if it is really a bad chain of brake pads, it can generally be heard.

Because most of the brake pads are designed with alarm pads, if there is a slight sound of "iron rubbing iron" while tapping the brake, it is the sound of the brake alarm pads, indicating that the brake pads are too thin, and the brake pads must be replaced immediately. Otherwise, if the alarm blade is rubbed against the brake disc for a long time, there will be a nuclear tremor mark, which will permanently destroy the brake disc and reduce the safety factor.

My brake discs grind like this. Can I continue to use the brake pads after changing them?

Dear, the inquiry ** is too serious.

I just can't use it.

Yes, dear.

What do you mean, no, can you continue to use the brake pads for a while after changing them? I've been poor lately and have no money.

Kiss, no, it's too serious.

It is dangerous to continue using it.

Brake pads, also known as "brake shoes" or "brake pads", although the volume is very small, but it affects the distance of the last few meters, brake pads are known as the most basic and important wearing parts of the active safety system, every time you press the brake pedal brake pads will wear out once, when worn to the limit position must be replaced, otherwise it will reduce the effect of braking, and even cause safety hazards. So do the new brake pads have to be run in?

1. The new brake pads must be run-in.

2. After replacing the new brake pads, it does not mean that the braking effect will be better, and the new brake pads need to go through a running-in period in order to play the maximum braking effect.

3. After the brake pads are replaced, if you feel that the brakes are soft, you must step on the brakes a few times to eliminate the gap between the brake pads and the brake disc. It takes 200 kilometers to achieve the best braking effect, and try to drive to a place with good road conditions and few cars.

The run-in method of the new brake pads is to use the split point brake for braking as much as possible, and do not use the sudden brake before the run-in is good.

Brake discs and brake pads do not have to be replaced together, it depends on the situation, because brake pads are damaged more often than brake discs. Usually, the brake pads are changed every 30,000 kilometers, and the disc is replaced every three times. The replacement check is to touch the surface of the brake disc with your hands, the new brake disc is smooth, if the brake disc has a very obvious scratch feeling when touched by hand, and the depth of scratches on the surface of the brake disc is different, then it is recommended to replace the brake disc.
