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:
1. Core factors of price differences
(1) Material cost (affecting performance and lifespan)
Material type characteristics, price impact, applicable scenarios
Half metal (low-end) containing iron and copper powder, low cost, but prone to wear and tear, poor high-temperature performance (200-500 yuan), light trucks, low load engineering vehicles
Sintered metal copper/iron-based sintering, high temperature resistant, wear-resistant medium (500-1500 yuan) heavy-duty trucks, mining machinery
Ceramic composite ceramic fiber+high carbon material, low noise, high temperature resistance, long life (1500-3000 yuan) for mining trucks and special engineering vehicles
Conclusion: The higher the material (such as ceramics/sintered metals), the higher the price, but the lifespan and safety are significantly improved.
(2) Manufacturing process (affecting reliability and stability)
Cold pressing molding (low-cost): The process is simple, but the density is low, and it is prone to cracking or thermal degradation.
Hot pressing sintering (high cost): High temperature and high pressure forming, tighter structure, and better high temperature resistance (such as Tymington TMD process).
Laser slotting/chamfering: optimizes heat dissipation and chip removal, reduces braking noise (such as Brembo technology).
Conclusion: Craft brake pads are more expensive, but they provide more stable braking and lower failure rates.
(3) Brand premium and certification (affecting trust)
International brands (such as TMD, Brembo):
High price (1000-3000 yuan/set), but certified by ISO 7881 and WABCO, suitable for engineering vehicles such as Volvo and Mercedes Benz.
Domestic affordable brands (such as Xinyi and Jinqilin):
The price is low (200-800 yuan/set), and some parts comply with the national standard (GB 5763), but the high-temperature performance may be weaker.
Conclusion: The brand premium reflects quality assurance, but it needs to be selected based on specific needs.
2. Potential risks of low-priced brake pads
(1) Safety hazards
Severe thermal degradation: There is a high risk of brake failure during long downhill driving (as shown in the investigation of truck accidents in Yungui Mountain area, some low-priced brake pads have a friction coefficient decrease of more than 50% after continuous braking).
Rapid wear and tear: Poor quality materials may require replacement after 30000 to 50000 kilometers (products can reach 100000 to 200000 kilometers), resulting in higher long-term costs.
(2) Damage to other components
Abnormal wear of brake discs: Hard metal impurities may scratch the disc surface, and the cost of replacing brake discs is much higher than that of brake pads.
Brake system malfunction: Poor quality brake pads may cause problems such as cylinder jamming and ABS false triggering.
How to balance price and quality?
(1) Select by usage scenario
Light engineering vehicles (such as small loaders): can choose domestic mid-range brands (such as Xinyi), priced at 500-800 yuan/set.
Heavy duty mining trucks/long-distance logistics vehicles: It is recommended to use international brands such as TMD and Brembo, with a price range of 1500-3000 yuan per set, but with higher safety.
(2) Focus on key indicators
Friction coefficient (preferably above 0.4)
High operating temperature (at least 600 ℃)
Certification standards (such as ISO 7881, GB 5763)
(3) Long term cost accounting
Unit price of brake pad type (yuan/set) Replacement cycle (10000 kilometers) Total cost of 100000 kilometers (yuan)
Low price domestic film 300 3 1000 (replaced 3 times)
Imported film 2000 15 2000 (replaced once)
Conclusion: Brake pads have a high single investment, but they are more cost-effective in the long run and significantly improve safety.
4. Suggestions
Prioritize choosing legitimate brands such as TMD, Brembo, and Federal Mogul to avoid "three no products".
Products under extreme working conditions (mining, long downhill), otherwise maintenance and accident costs far exceed the price difference of brake pads.
Compare prices through e-commerce channels (such as JD Industrial Products and Alibaba), but ensure official authorization to avoid counterfeit goods.
Summary: "You get what you pay for" in engineering vehicle brake pads. In terms of safety and durability, high priced products are usually more reliable, but it is necessary to choose a cost-effective solution based on specific needs.
