Three Maextro V800 luxury MPVs reportedly suffered complete brake-pedal bracket failures during emergency-stop testing in China, according to a video report by automotive outlet Dongchedi cited by CarNewsChina. The Huawei-JAC collaboration’s vehicles were tested on a closed course, braking from 100 km/h to a stop. Each of the three cars failed: one on its third attempt, another on its fourth, and the third during its second full-force stop.
Pedal-force sensor readings showed that the third vehicle’s component broke at 1,612 N. The report said the national standard requires a brake pedal to withstand 2,000 N for five seconds without failing; another recorded maximum force before failure reached 4,589 N. Initial analysis pointed to possible structural weaknesses, including the pedal’s distance from its pivot and a single vertical support layer. Inspectors also noted weld marks in a highly loaded area, thin material and a lack of reinforcement ribs.
After the bracket broke, the vehicles lost normal foot-brake function and had to rely on the transmission’s Park position for emergency deceleration. Testing reportedly showed stopping distance increasing from about 38 metres to roughly 140 metres. The V800 manual cautions that using Park to slow the vehicle cannot fully replace conventional braking and carries a significant risk of losing control. Maextro and manufacturing partner JAC Motors had not issued an official statement or investigation findings at the time of the report.
