Abstract: Through the study of disc brakes, a mechanism based on Hall sensors is designed that can be used to monitor the remaining usable thickness of disc brake friction pads. Firstly, through the analysis and study of the spatial structure of the disc brake, the monitoring device is designed, and the three-dimensional model of the monitoring device and the main parts of the disc brake is drawn by CATIA software. Then, by analyzing the installation and use of Hall sensors, the circuit system is built with Proteus software. Finally, the monitoring principle is analyzed and encoded with Keil, and the file is uploaded to the microcontroller system. Through simulation, it is found that the cooperation between the complete mechanical device and the single-chip microcomputer system can achieve the purpose of real-time monitoring of brake thickness.
