What is the relationship between car brake pads and muffler spacers?

OEM brake pads are called OEM anti-noise shim
It is a thin layer of accessories attached to the back of the brake pads by selecting composite materials through bench tests when developed by OEM brake pad factories and OEMs, mainly for shock absorption and noise reduction. Therefore, the brake pads of each model are different according to the brake pad materials, and the selected composite materials are different, which are provided by professional sealing material manufacturers. The machining accuracy requirements are relatively high.
Car brake pads, also known as brake shoes, are consumables that will gradually wear out during use. When worn to the limit, they must be replaced, otherwise the braking effect will be reduced, and even safety ACCIDENT. The main function of the brake pad muffler pad is to reduce the noise during friction. Noise elimination principle of automobile brake pad muffler pads: Brake pad muffler pads use different methods to eliminate braking noise according to the noise distribution. The commonly used method is to add accessories such as springs and gaskets.
This spacer is the brake pad muffler pad. A buffer between the friction part of the brake pad muffler pad and the chassis can eliminate braking noise. Even change the friction material formula. Change the output size to completely eliminate the noise.
There are two types of brake pads: metal brake pads and carbon ceramic brake pads. Brake pads are also called brake pads. In the braking system of a car, the brake pads are the key safety parts, and the brake pads play a decisive role in the quality of all braking effects. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The working principle of the brake mainly comes from friction. The friction between the brake pad and the brake disc and the tire and the ground is used to convert the kinetic energy of the vehicle into frictional heat energy 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 capabilities 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-pump to avoid hydraulic failure and brake recession caused by high heat.
