Brakes failing during races happened in the past as well, not that there were many instances of it. If something like this did happen, it was brushed off as the racer having bad luck. There was another possibility that was tacit knowledge to everyone but would never be verbalized, of course—an intentional doing.
Racing was not only a dangerous and thrilling game, plenty of unknown deals happened under the table in the racetracks. Actually, people knew about this as well.
Once there was a brake failure, the unlucky racer would usually die or sustain severe injuries. Similar incidents happened in Yuanbao Mountain previously and were found to be no fewer than five times. Any racer whose brakes failed were gravely injured even if they did not die; two out of five died while those who survived were paralyzed.
