Technical Field
[0001] The utility model relates to the technical field of brake pads, in particular to a drum brake pad for an automobile that is stable in use. Background Art
[0002] As we all know, automotive drum brake pads are a key component in the braking system and are usually used in the rear wheel braking system of the car, especially in some older vehicles or commercial vehicles. They are used in conjunction with the brake drum structure of the wheel to slow down or stop the vehicle through friction. Drum brake pads are usually semi-circular and are located inside the wheel. When subjected to the pressure of the braking system, they slow down the vehicle through friction. This braking system is usually not as superior to the disc brake system commonly used in modern vehicles in terms of performance and braking efficiency.
[0003] However, the existing automobile drum brake pads have poor heat dissipation effect, and the heat is not easy to dissipate quickly, which will cause the heat to be transferred to other components and cause the brake mechanism to become unstable. Utility Model Content
