This study investigates the influence of wheel rotational speed and brake pad material on the temperature of disc braking systems. The experimental setup incorporates an LM393 speed sensor and a MAX6675 thermocouple temperature sensor, both interfaced with an Arduino microcontroller, with data output displayed via a MATLAB GUI and an LCD screen. Testing was conducted in three repetitions across four rotational speed variations (1000, 1500, 2000, and 2500 rpm) and three types of brake pad materials: standard, semi-metallic, and full-metallic. The results indicate a direct correlation between rotational speed and braking temperature. At 2500 rpm, the highest temperatures recorded were 83.3°C for full-metallic pads, 59°C for semi-metallic pads, and 47°C for standard pads. These findings confirm that both the pad material and wheel speed significantly affect the heat generation during braking.
