Sasuke doesn't surpass Madara in terms of Chakra. Madara literally had Six Paths Senjutsu and two Rinnegan and was a Ten-Tails Jinchuriki. There's absolutely no way Sasuke has ever had more chakra than Madara. I'm not sure Madara was ever shown being exhausted at all in the series except for when Hashirama stabbed him from behind. Madara was just spamming everything during the war, even after losing his Edo Tensei body. Sasuke's chakra at any point in the manga doesn't compare. Even when Sasuke forcibly took all the chakra from the TB he entombed and channeled it into his Susanoo, it still wouldn't compare to Madara's chakra as a TTJ.
