disc type The braking principle and workflow of the brake pad

1. The working principle of the disc brake is that when braking, the oil is pressed into the inner and outer cylinders (sub-pump), and its piston presses the two brake blocks under hydraulic action to generate friction moments to brake. At this time, the edge of the rectangular rubber seal in the wheel cylinder groove produces a small amount of elastic deformation under the action of piston friction.

2. The working principle of the disc brake can be described as a disc. When you pinch the rotating disc with your thumb and forefinger, the disc will also stop rotating.Disc brakes are sometimes also called disc brakes, which are divided into ordinary disc brakes and ventilated disc brakes.

3. The braking principle of disc brake pads is based on the generation of friction. It consists of the following main components: brake discs, brake calipers, brake pads and brake hydraulic systems. Brake disc: The brake disc is a disc-shaped metal part installed on the wheel.

4. The working principle of disc brake pads. First of all, disc brake pads are composed of two main parts: brake pads and brake discs. Brake discs are generally made of metal and installed on wheels. And the brake pads are installed in the brake caliper and close to the brake disc.

5. Detailed explanation of the structure and working principle of disc brake pads. The structure of disc brake pads mainly consists of three parts, namely substrate, friction material and binder.

What does car brake disc mean

1. Simply put, the brake disc is a round plate. It also rotates when the car is driving. It works together with the brake caliper and brake pad. When we step on the brake, we rely on the brake caliper and brake pad to clamp the brake disc to slow down or stop.

2. Disc brakes are also called disc brakes. There are two types of disc brakes and ventilation disc brakes. The brake disc size of the ventilated disc brake is large, and there are regularly arranged ventilation holes on the disc. The long-distance brake has less thermal attenuation, and the brake is sensitive, but the cost is relatively expensive.

3. Brake disc. After checking the official website of the brake disc, it is learned that the car brake disc, also known as the brake disc, is mainly made of metal and has many air outlets on it. Its shape is round like a disc disc, and there is a small circle inside.A car refers to a transport vehicle powered by a flammable gas, and also refers to a vehicle driven by its own equipment.

How to deal with car brake discs with grooves

If the brake disc has grooves, you can consider polishing the brake disc or Replace the brake disc. If the groove of the brake disc is relatively slight, you can directly remove the brake disc and smooth the surface with coarse sandpaper.The groove of the brake disc is relatively deep, and it is recommended to replace the new brake disc directly. The brake disc is a consumable, and it is normal to have grooves.

The repair method for grooves in the brake disc is to sand or replace it directly. The circular groove on the surface of the brake disc is mainly caused by the existence of hard spots on the surface of the brake disc or the abnormal wear of the brake disc due to the entry of foreign objects such as fine sandstone between the brake pad and the brake disc during the driving process of the vehicle.

If the groove is not very serious, the brake disc can continue to be used. If the groove is very deep, it is recommended that the rider replace the brake disc. If the brake disc of the car is used normally, it can be used for 80,000 to 100,000 kilometers. Brake pads are also parts that need to be checked and replaced regularly.

If the groove is very deep, it is recommended that car enthusiasts replace the brake discs.The brake disc of the car can be used for 80,000 to 100,000 kilometers if used normally.

The brake disc has grooves that can be flattened. The uneven surface of the brake disc and the grooves will affect the brake performance. For example, when you step on the brake and the steering wheel shakes when driving. After grinding, it can be used normally, but after grinding, the thickness of the brake disc must be measured. If it is lower than the specified wear limit, it should be replaced in time.

What material is the brake disc made of

The brake disc is usually made of carbon fiber ceramic and metal cast iron material. According to the configuration information of Ampude Automobile, as of October 4, 2022, the brake discs of Ampude Automobile are usually made of carbon fiber ceramic and metal cast iron.Ampde Brake Disc is one of the largest auto parts chain brands in China.

The materials of brake pads mainly include: sintered (copper-based sintering or copper-based), KEVLAR&CARBON, organic, semi-metallic, etc.

The material of the brake disc adopts China's gray cast iron 250 standard. The requirements of the three main elements of chemical composition are: C: 1∽4 Si: 9∽3 Mn: 0.6∽0.9.

Carbon material brake disc is a special material of carbon lattice and carbon fiber synthesis, which is used on F1 racing. Carbon ceramic brake discs have almost become one of the essential logos for high-performance vehicles, and are used in high-speed trains, airplanes and other fields that require high-performance brakes, but this does not mean that the only choice for the best braking is carbon ceramic brakes.

How to solve the abnormal sound of the car brake disc

1. (1) Clean the surface of the brake pad: If the abnormal sound of the brake pad is caused by dust and dirt, it can be solved by cleaning the surface of the brake pad. Cleaning the surface of the brake pad with soapy water or special detergent can make the surface of the brake pad smooth and reduce abnormal noise.

2. If you think the friction sound is harsh, you can also ask the repairman to polish the brake pads, so that there will be no abnormal sound when stepping on the brake. The second situation is that after the car passes through the mud and sand road, the mud and small stones enter the brake, so we will hear the harsh sound of "hiss" when we step on the brake.

3. Like many parts on cars, brake discs also have a "brin period".

The function of the brake disc

The brake disc provides a friction surface for the brake pad and generates friction with the brake pad, so as to ensure driving safety. When the brake disc provides a friction surface, it will also be worn. When the wear reaches the limit value, it must be replaced in time. The brake disc is too thin and will break in case of emergency braking.

Simply put, the brake disc is a round plate, and it also rotates when the car is running. It works together with brake calipers and brake pads. When we step on the brake, we rely on the brake caliper and brake pad to clamp the brake disc to slow down or stop.

The brake discs are definitely used for braking, and their braking power comes from the brake calipers. Generally speaking, most brake calipers are basically fixed to the part where the inner brake piston pump is located, and the outer side is a caliper structure.The inner brake pad is fixed on the piston pump, while the outer brake pad is fixed on the outside of the caliper.

The brake disc is usually made of high-temperature alloy steel, which has good wear resistance, thermal conductivity and thermal expansion resistance. Brake Pad is a friction material that is in close contact with the brake disc. Brake pads are generally composed of two parts: steel plate and friction material.
