Can Somai titanium based ceramic brake pads be used with Haval H2

Yes, ceramic brake pads work well.

1. The car has 8 pieces, and one wheel of the car needs two brake pads.

2. The front and rear do not need to be together, the left and right must be changed together, and when you buy it, it is also a pair of brake pads (both left and right) to change the brake pads, not to change the front and rear at the same time, in general, the left and right are changed together, and the front and rear replacement has nothing to do with the replacement of tires.

The front disc rear bulge car is generally replaced by three pairs of front brake pads, and a pair of rear shoe pads is replaced.

The parking brake and foot brake are 8 pieces in one, if not, it is 12 pieces.

Brother, there are a total of 8 pieces in the front and rear of your car, if you change it, first of all, you look at the wear and tear of the brake pads, generally the back wear is not very serious, you can replace the front, next time you can change the front and back together.

There are 8 in total, and there are 2 in each wheel, if you change them, it is best to look at them all to see the degree of wear

Depending on the degree of wear, there are three options: 1. Either change the first two wheels; Second, either change the last two rounds; Three, or four rounds of full change. (It's completely possible to change only the front wheel, never just one round).

There are two on each wheel.

It is possible to change only a certain tire.

Generally, the front wheels of the trolley wear out faster than the rear ones.

But when you change a tire on the front wheel, you have to consider whether the other front wheel is going to be replaced with the rear wheel, and the same is true.

8 pieces: 2 pieces per wheel. Each set of 4 tablets is provided.

Look at what kind of car, generally there are two on each wheel.

Now the asbestos material has basically been eliminated. There are three main categories on the market: "multi-metal brake pads", "less metal brake pads", and "organic brake pads".

According to the actual use effect, the last category, that is, the "organic brake pad" has the best performance, such as the popular ceramic fiber brake pad.

The brake pads of the car are non-asbestos friction materials, and they are generally replaced once every 80,000 kilometers.

Under normal circumstances, if you travel more than 80,000 kilometers, the brake pads need to be replaced. Brake pads according to the model and brake pad material, the brand is not the same, the cost of replacing 4 brake pads is generally about 650 yuan to 800 yuan. Generally between one hundred and three hundred.

Brake pads will produce instantaneous high temperature during braking, especially when driving at high speed or emergency braking, the friction coefficient of the friction pads will decrease at high temperatures. And look at the friction coefficient when purchasing, the friction coefficient determines the basic brake pad braking torque.

What are the advantages and disadvantages of brake pads made of different materials? Today is a long time to see.

Brake pads are classified according to the material, which can be divided into four categories:

1. Asbestos brake pads (due to environmental protection and temperature control problems, they have been eliminated);

2. Semi-metallic mixed brake pads (noisy, great damage to the brake disc);

3. NAO brake pads (less thermal attenuation, less noise, less wear, good performance, mainstream choice);

4. Carbon fiber brake pads (generally used for high-end cars or sports cars).

There are two types of brake pads: metallic brake pads and carbon-ceramic brake pads. Brake pads are also called brake pads, in the braking system of automobiles, brake pads are key safety parts, and all brake effects are decisive for brake pads.

Brake pads are generally made up of steel plates, bonded insulation, and friction blocks. The working principle of brakes mainly comes from friction, using the friction between brake pads and brake discs and tires and the ground to convert the kinetic energy of the vehicle into the heat energy of friction to stop the car. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capacity to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and each sub-cylinder, so as to avoid hydraulic failure and brake decline caused by high heat.

Brake pads are now mainly divided into the following categories:

Asbestos brake pads (basically eliminated), semi-metallic brake pads, less metal brake pads, NAO formula brake pads, ceramic brake pads, NAO ceramic brake pads!

In addition, no matter what material the brake pads are, there are the following materials:

Adhesive + Fiber + Filler + Conditioner + Friction Booster + Lubricant.

Divide the disc test brake system and drum test brake system, divide the oil circuit and air brake, and there is the connecting bar.

Remember to adopt it.

Hello, automobile brake pads, also known as automobile brake pads, refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel, in which the friction lining and friction lining bear external pressure, resulting in friction to achieve the purpose of vehicle deceleration. Hope to adopt!

Brake pads are also called brake pads, brake pads are the most critical safety parts in the brake system of automobiles, and all brake effects are decisive for brake pads, so good brake pads are the protectors of people and cars. Generally, according to the type, it can be divided into drum type and disc type.

The normal brake pads of the car should be more than 5 mm.

If it's less than 5 mm, you'll need to change the brake pads.

a Asbestos type brake pads (replaced by NAO type due to carcinogenic risk).

b Asbestos-free friction materials are divided into the following categories:

a) Semi-metallic friction materials for disc brake pads used in passenger cars and heavy-duty vehicles. Its material formula usually contains about 30% to 50% of ferrous metal (such as steel fiber, reduced iron powder, iron foam powder). Semi-metallic friction materials get their name from this.

It is the first asbestos-free material to replace asbestos and develop. Its characteristics: good heat resistance, high absorption power per unit area, large thermal conductivity, can be applied to the braking conditions of the automobile in high-speed, heavy-load operation.

However, it has disadvantages such as high braking noise and brittle corners.

b) NAO friction material. Broadly speaking, it refers to non-asbestos non-steel fiber type friction materials, but the existing disc also contains a small amount of steel fibers. The base material in NAO friction materials is in most cases a mixture of two or more fibers (in the form of inorganic fibers and a small amount of organic fibers).

Therefore, the NAO friction material is a non-asbestos mixed fiber friction material. Generally, the brake pads are chopped fiber type friction plates, and the clutch plates are continuous fiber type friction plates.

c) Powder metallurgy friction materials. Also known as sintered friction material, it is made of iron-based and copper-based powdery materials by mixing, pressing, and sintering at high temperatures. Suitable for braking and transmission conditions at higher temperatures.

Such as: aircraft, trucks, heavy construction machinery braking and transmission. Pros:

Long service life; Disadvantages: high product quality, large braking noise, heavy and brittle, large dual wear.

d) Carbon fiber friction material. It is a type of friction material made of carbon fiber as a reinforcing material. Carbon fiber has the characteristics of high modulus, good thermal conductivity, and heat resistance.

Carbon fiber friction materials are one of the best performing among various types of friction materials. The carbon fiber friction pad has high absorption power per unit area and light specific gravity, which is especially suitable for the production of aircraft brake pads, and the brake pads of some high-end cars abroad are also used. Because it is expensive, its application range is limited, and the production volume is small.

In the composition of carbon fiber friction materials, graphite, a compound of carbon, is used in addition to carbon fiber. The organic binders in the components are also carbonized, so carbon fiber friction materials are also called carbon-carbon friction materials or carbon-based friction materials.

The main thing to see is that the thickness of the brake pads is less than 50-20mm, so you need to replace it immediately. The thickness is shown in the figure

The replacement time cycle of brake pads is not fixed, it depends on the road conditions of the vehicle, the frequency and strength of the driver pressing the brake pedal, generally speaking, the life of the brake pads of the front brake is 35,000 kilometers, and the life of the rear brake pads is 6-10w kilometers, so it is recommended to check the front brake pads every 30,000 kilometers.

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.

Q: How long is the replacement cycle of brake pads?

A: Usually we will use whether the brake warning light on the dashboard is on as the basis for replacing the brake pads, but this is the final bottom line. Although all vehicles have this warning system, some directly sense the thickness of the brake pads, and some are completely worn out, and the extreme drop in brake fluid will make the warning light illuminate.

Therefore, it is necessary to check whether the brake pads can be used at each factory maintenance, and replace the brake pads that are close to the end of life early, rather than just believing the warning lights.

Brake pads are consumables, which will gradually wear out in use, and must be replaced when worn to the limit position, otherwise the effect of braking will be reduced, and even cause safety accidents.

In general, the front brake shoes wear out relatively quickly, and the rear brake shoes are used for a relatively long time. In daily maintenance, it should be noted that under normal driving conditions, check the brake pads every 5000 kilometers, not only to check the remaining thickness, but also to check the state of 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, and the brakes must not be replaced when the friction material part is worn out.

Some vehicles have a brake pad alarm function, once the wear limit is reached, the instrument will alarm and prompt replacement.

In addition, some consumers like to replace brake pads at any repair shop. In fact, when replacing, the brake pads provided by the original spare parts should be replaced, so that the braking effect between the brake pads and the brake disc is the best and the wear is minimal. When replacing the brake shoes, the brake cylinder must be pushed back with a special tool.

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.

After replacing the brake pads, be sure to step on the brakes a few times to eliminate the gap between the shoe pads and the brake disc, resulting in the first foot not braking, which is prone to accidents. In addition, it takes 200 kilometers to achieve the best braking effect, and the brake pads that have just been replaced must be driven with caution.

Generally 60,000 kilometers to change, I'm talking about the intermediate sedan, the brake pads do not have a specified time, generally you feel that the brake pedal will be lower and lower when driving, to regularly repair the car to check, so good for the car, your car 26,000 kilometers on the change, your car is not automatic?

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

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.

Normal, there is no hard standard, the main thing is to look at the degree of wear. Generally around 40,000. Generally 26000 is not needed, depending on your own wear and tear of course. If you don't understand, you may have been fooled.

Normal driving, the frequency of replacing the brake pads of the car is generally about 30,000 kilometers, if the driving habits are not very good, you should often check yourself, and the brake pads should be replaced when they become thinner. If you want to change the brake pads, you can take a look at the "car ant". They work with all the big and small stores in the country.

Generally speaking, the replacement cycle of the front brake pads is 30,000 km, and the replacement cycle of the rear brake pads is 60,000 km. Different models and different driving habits tend to vary greatly, so the actual inspection results should prevail.

A new brake pad thickness (excluding the thickness of the brake pad steel backplate) is generally about 15 20mm, when the naked eye observation brake pad thickness has only left the original 1 3 thickness (about 5mm) or so, the owner will increase the frequency of self-inspection, ready to replace at any time, usually less than 3mm thickness when the need to replace immediately. Each brake pad has a protruding sign on both sides, and the thickness of this logo 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. At present, many models will prompt the position of the instrument handbrake light when the brake pads are too thin, which is relatively convenient for self-inspection.

Look at the existing thickness of your brake pads, no less than 3mm is OK, I also found relevant information on the Internet, haha, now to teach you. I changed the base macro brake pads, the performance is still very good, ** can be bought on the very convenient. Hope it works for you.

Brake pads are not fixed how often to change the statement, it depends on the driving road conditions and driving habits, these habits will affect the use of brake pads, if you can grasp it well, you will find that many times there is no need to step on the brakes, a pair of brake pads are used well, can reach 100,000 kilometers.

The approximate service life of brake pads is about 5 to 60,000 kilometers, and it is related to driving habits, so it is recommended to check the oil maintenance time.

Generally, car manufacturers have a recommended mileage, 60,000 or 80,000 kilometers. However, according to the actual usage, my brake pads were exchanged for 120,000 yuan.
