4 pcs MTB bike cycling disc brake pads semi-metallic brake

Brake pads are also called brake pads. In the braking system of a car, the brake pad is the most critical safety part, and the brake pad plays a decisive role in the quality of all braking effects, so it is said that a good brake pad is the protector of people and cars.
Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates are coated to prevent rust. During the coating process, the SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process to ensure the quality. The thermal insulation layer is composed of materials that do not transfer heat, and the purpose is to insulate. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, so as to achieve the purpose of decelerating and braking the vehicle. Due to friction, the friction pads will gradually wear out. Generally speaking, the lower the cost of the brake pads, the faster they will be worn. Car brake pads are divided into types: - brake pads for disc brakes - brake shoes for drum brakes - to pads for large trucks
Brake pads are mainly divided into the following categories: metal brake pads and carbon ceramic brake pads, of which metal brake pads are further divided into less metal brake pads and semi-metal brake pads, ceramic brake pads are classified as less metal, and carbon ceramic brake pads are Used with carbon ceramic brake discs. The working principle of the brake is mainly from friction. The friction between the brake pad and the brake disc (drum) and the tire and the ground is used to convert the kinetic energy of the vehicle into the heat energy after friction and 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, and avoid hydraulic failure and brake recession caused by high heat. Brake pad replacement depends on how long your shims have been in the life of your car. Generally, if you have a distance of more than 80,000 kilometers, the brake pads need to be replaced. However, if you hear rubbing noises from your wheels, no matter what your mileage, you should replace your brake pads. If you're not sure how many kilometers you've driven, you might go to a store that replaces pads for free, buy brake pads from them or go to a car service to have them installed.
