Chinese authorities are investigating brake-pedal bracket failures reported during emergency-braking tests of the Maextro V800, a luxury minivan developed by Huawei and JAC. The tests, conducted on a closed track and shown in a video released by automotive outlet Dongchedi, involved three separate vehicles braking from 100 km/h to a stop. The bracket broke on all three: during the third attempt for one vehicle, the fourth for another, and the second full-force braking attempt for the third.
Pedal-force sensor data showed a maximum reading of 4,589 newtons before a failure, while the third vehicle’s bracket reportedly broke at 1,612 newtons. Testers noted that China’s national requirement calls for a brake pedal to withstand 2,000 newtons for five seconds without failing.
China’s Ministry of Industry and Information Technology said it would join the Cyberspace Administration of China and the State Administration for Market Regulation in a joint investigation. Maextro said it would cooperate. The company has previously said it knows of no such failures in customer use since deliveries began, describing the video’s scenario as an extreme, non-standard test. It also said its braking system was developed and validated to exceed national and industry requirements, while pledging to redesign the bracket, provide current owners with a free upgrade, and strengthen design validation, testing parameters and production quality management.
