Suggestions for Selection and Maintenance of Copper-based Brake Pads
Key Points for Purchase
Application scenarios: Copper-based brake pads are preferred for high-speed and high-temperature environments; ceramic pads can be chosen for urban commuting to reduce noise.
Certification standards: Products certified by EU ECE R90 have a 20% lower wear rate and a 15% longer service life than non-certified products.
Maintenance Notes
Replacement cycle: It is recommended to inspect copper-based brake pads every 15,000-20,000 kilometers. They need to be replaced when the thickness is less than 3mm to avoid damage caused by direct contact between the metal layer and the brake disc.
Cleaning and maintenance: Regularly clean the copper debris in the brake calipers with a high-pressure air gun to prevent jamming from affecting the braking response.
Summary
Copper-based brake pads, with their excellent high-temperature performance and thermal conductivity, remain the preferred material in the field of high-performance braking. However, restrictions from environmental regulations are promoting their development towards low-copper and composite materials. In the future, with the application of new materials such as graphene, copper-based brake pads are expected to meet more stringent environmental requirements while maintaining their performance, and continue to play a key role in fields such as rail transit and new energy vehicles.
