What form do car brake pads come in? How many types of car brake pads are there?

Simply put, drum brakes and disc brakes, drum brakes have low cost, and are used for small cars, mini cars have more rear wheels, while compact cars, intermediate cars and luxury cars are basically disc brakes front and rear

At present, there are two mainstream types of disc brake pads and drum brake pads.

Brake pads are divided into drum brake pads and disc brake pads according to the brake system, and the brake efficiency of the drum type is low, so the market is basically disc-shaped.

According to the material, it is divided into asbestos type, semi-metal type, and non-asbestos organic type.

The asbestos type has been eliminated, mainly because 1. asbestos is medically recognized as a carcinogen, 2. asbestos has poor thermal conductivity, and repeated braking will accumulate a large amount of heat, which will then lead to serious thermal attenuation, resulting in brake failure and danger.

The semi-metal hybrid brake pad has a high metal content inside, so the strength is high, but the friction of the brake pad is smaller than that of asbestos, and the vehicle needs a higher braking force to achieve the same braking effect, so the noise is high and the wear is high when braking.

Non-asbestos organic brake pads, referred to as NAO brake pads, are made of glass fiber, aromatic polyester fiber and other fibers such as carbon or pottery as reinforcement materials, to achieve the purpose of long service life and durability, but the cost is higher than the first two.

In terms of brake type, it can be divided into: brake pads for disc brakes, brake shoes for drum brakes, and liner pads for large trucks. From the material, it can be divided into:

Resin-based brake materials, powder metallurgy brake materials, carbon-carbon composite brake materials, ceramic-based brake materials. The brake drum is equipped with brake shoes, so the disc brake pads are used to specifically indicate that the brake pads are installed on the disc brakes.

Classification of brake pads:

1. Semi-metallic brake pads, basically all the brake pads when they leave the factory are this formula, of course, this brake pads are also the cheapest drawings, the friction coefficient of this brake pad is low, the general friction coefficient is shorter, and some manufacturers make this kind of brake pads have a high friction coefficient, of course, this is also a disadvantage of noise. Generally, this kind of brake pad is easy to produce noise when used in Japanese cars, and of course, this is also inseparable from the brake disc.

2. Less metal brake pads, this brake pad ** slightly higher than semi-metal, of course, the performance will be higher, this formula brake pad belongs to the mid-range, but in the eyes of consumers is not recognized, in fact, this brake pad is still very cost-effective, of course, it is difficult for consumers to distinguish the difference between this brake pad and semi-metal brake pad, so it is difficult to choose.

3. Ceramic brake pads: the raw materials used in ceramic brake pads of different manufacturers are not the same, which also leads to the difference in ceramic brake pads themselves, and the difference in ceramic fiber has also led to the advantages and disadvantages of ceramic fibers. Real ceramic brake pads also contain aramid fibers, which are far superior to the above formula brake pads in terms of service life and brake pad performance.

Of course, it is also more expensive.

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).

One of the brake pads of the car is disc brake pads, and there is a drum brake pad, large cars generally use drum brakes, the advantage of drum brakes is that the use cycle is long, the braking effect is good, the brake pads are cheaper than the disc type, the disadvantage is that the heat dissipation is not good, the brake effect will decline if the brake is used for a long time, and most of the small cars use disc brakes, the braking effect is good, the disadvantage is expensive, and every time the brake pads are replaced, it is a lot of money.

Automobile brake pads, also known as automobile brake pads, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheels, and the friction lining and friction lining bear external pressure to produce friction to achieve the purpose of vehicle deceleration.

Hello, by the material most common there is graphite. and ceramic, according to the structure, there are most often disc brake pads and drum brake pads.

There are two main types of car brakes, drum brakes and disc brakes, i.e., disc brakes.

Disc brakes are divided into: solid discs, hollow discs, perforated discs, perforated and marked discs.

According to the material of the brake disc, it is divided into: cast iron brake disc, carbon fiber brake disc and the current top ceramic porcelain brake disc.

The disc brake is waterproof, and the Zheng belt brake effect is good, and it is mostly used in low, medium and high-end cars.

Drum brakes: generally used for medium or heavy trucks, buses, etc.

Compared to the same period last year, the brakes of the car are quite important. Regarding driving safety, 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 wheels. Friction linings and friction pads withstand external pressure, which produces friction, and then achieves the purpose of deceleration of the car.

What are the classifications of automobile brake pads: semi-metallic brake pads?

Semi-metallic brake pads, which are basically the brake pads of all cars leaving the factory, are of course the cheapest drawings. These brake pads have a low coefficient of friction and most of them have a short service life. Some manufacturers have already manufactured these brake pads with a high coefficient of friction.

Of course, this also has drawbacks and is prone to noise. Most Japanese cars use these brake pads, which are prone to noise. Of course, this is also closely related to the brake discs.

What are the categories of automotive brake pads: less metal brake pads?

Metal brake pads are relatively rare. Of course, the ** of this brake pad is slightly higher than that of semi-metallic brake pads. Of course, the performance of this brake pad will be a little higher.

The brake pads of this formula belong to the mid-range, but are not recognized by consumers. I think this brake pad is still very cost-effective. Of course, it is difficult for consumers to distinguish the difference between this brake pad and semi-metallic brake pads, so it is difficult to choose, which is why consumers do not recognize this formula (this formula applies to any car system).

What are the categories of automotive brake pads: aramid copper fiber brake pads?

Copper fiber aramid brake pads, this formula brake pads are better than the above two, of course, the best and performance is also high, good manufacturers will add aramid to this formula brake pads (aramid is a hard material for bulletproof vests). The ** of aramid fibers is also very high, and in the case of copper and aramid fibers, the service life and braking performance of brake pads are greatly improved, which will not be briefly introduced here (this formula is suitable for any automotive system).

What are the categories of automotive brake pads: high-end ceramic brake pads?

High-end ceramic brake pads: There are many ceramic brake pads on the market, of course, there are imitations. The ceramic brake pads produced by different manufacturers are not necessarily the same, and the performance is basically the same.

Of course, ceramic fibers are indispensable among the raw materials for ceramic brake pads. Friends basically know that ceramics are very hard and wear-resistant. The difference in the raw materials used in the ceramic brake pads of different manufacturers also affects the differences in the ceramic brake pads themselves, and the differences also affect the advantages and disadvantages of ceramic fibers.

Of course, this difference is indistinguishable in the eyes of consumers, and even manufacturers can't tell whether the quality is good or bad after using it. Real ceramic brake pads also contain aramid fibers, which are basically superior to the above formula brake pads in terms of service life and brake pad performance. Of course, it's quite expensive!

That's it for today's car introduction. The above is the classification of automobile brake pads that are briefly introduced by automobiles. The key to how brakes work is friction.

With the help of the friction between the brake pads and the brake disc (drum) and the tires against the ground, the kinetic energy of the car is converted into heat energy after friction to stop the car. So compared to the year before, good brakes are still quite important. If you want to know more about cars, please pay attention to the Grasshopper.
