초록 The brake system is essential for safe vehicle operation. Any malfunction or failure of the brake system can lead to serious accidents such as injuries or death of occupants. If the brake system can be monitored in real time, the monitoring system can notify the driver of dangerous situations such as excessive wear of the brake pads or overheating of the brake disc. Fatal accidents can be prevented by reducing the risk of brake system malfunction or failure. In this research, a sensor capable of measuring brake pad wear and disk temperature in real time is proposed. The sensor consists of variable resistance and a thermocouple. Through the experiments on the developed sensor, it is confirmed that the brake pad wear error is less than 0.1 mm and the brake disk temperature error is less than 10 oC.
