Do the carbon ceramic brake discs on the Xiaomi SU7 Ultra require regular maintenance or replacement?
The carbon ceramic brake discs standard across the Xiaomi SU7 Ultra lineup boast exceptional wear resistance. Under normal conditions, their service life exceeds 500,000 kilometers. Even with frequent aggressive driving on the track, they offer a lifespan far surpassing steel brake discs and can essentially be considered maintenance-free/replacement-free under normal circumstances, so you can use them with confidence. These race-grade carbon ceramic brake discs have a maximum operating temperature of up to 1300 degrees Celsius and exhibit extremely strong resistance to thermal fade, meeting the demands of continuous track driving. Supported by this race-grade braking system, the Xiaomi SU7 Ultra achieves a 100-0 km/h braking distance of only 30.8 meters, and can perform 10 consecutive 180-0 km/h braking tests without degradation, demonstrating very powerful performance.
The only scenarios requiring your attention are before entering the track and after exiting it, or after usage accompanied by persistent temperature warnings, where you should inspect the brake discs. If issues such as surface flaking or abnormal wear occur, please park the vehicle in a safe location and immediately contact a Xiaomi Auto Service Center.
