The invention discloses a brake disc permanent thermal deformation measuring system and a data processing method, and the system comprises a brake inertia test bench and two groups of sensors, each group of sensors comprises at least two displacement sensors, the two groups of sensors are respectively arranged at the two sides of a brake disc, and the measuring points of all displacement sensors to the brake disc are located on the same radius. The brake inertia test bench is used for installing the brake disc and the sensor, real-time displacement value data acquisition is carried out on single-circle rotation of the brake disc through the displacement sensor so as to obtain the real-time single-side buckling deformation of the brake disc, the maximum and minimum values of the single-side buckling deformation before and after braking are taken, subtraction is carried out, and the braking accuracy of the brake disc is improved. According to the method, real-time data are collected, the maximum value of the re
