Brake noise not only affects the driving experience, but may also be a signal of safety hazards. The following are systematic troubleshooting and solution methods, covering key factors such as mechanical principles, material characteristics, and maintenance processes:

The brake pads of construction vehicles are directly related to the safety of vehicle braking and operating costs. Choosing the wrong ones may lead to brake failure, drum damage, and even major accidents. The following are professional level purchasing strategies:

　　The replacement cycle of brake pads for construction vehicles is influenced by multiple factors such as vehicle type, load capacity, road conditions, and driving habits, and is usually longer than that of passenger cars (due to their more durable design), but requires stricter inspection.

　　The prices of brake pads for construction vehicles vary greatly, ranging from low-priced domestic parts (such as 200-500 yuan/set) to high-end imported brands (such as 1000-3000 yuan/set). Price is closely related to quality, mainly reflected in materials, processes, durability, safety certification, and other aspects. The following is a specific analysis:

　　The brake pads of construction vehicles (such as trucks, excavators, loaders, etc.) differ significantly from those of passenger cars in terms of materials, structure, and usage environment. Their design focuses more on high strength, high temperature resistance, long service life, and adaptability to extreme working conditions.

　　The market demand for passenger car brake pads is influenced by various factors, including car ownership, development of new energy vehicles, increased consumer safety awareness, and regulatory policies.
