Abstract

Purpose – Brake failure on motorcycles, particularly on downhill roads, remains a critical safety hazard driven by thermal overheating, fluid degradation, and fluid loss that conventional single-parameter monitoring systems fail to detect comprehensively. This study developed and preliminarily evaluated an IoT-based multi-sensor monitoring system for real-time detection of hydraulic disc brake conditions on motorcycles. Methods – Using a Research and Development approach, the prototype integrates a Thermocouple Type K, a capacitive moisture sensor, a Level Sensor K-0135, and a GPS BN-220 connected to an ESP32 DevKit V1 microcontroller with MySQL database and Laravel 12 web dashboard integration. Validation included laboratory calibration, 40 scenario classification tests, 50 response time measurements, and field testing on flat and downhill roads. Findings – All sensors achieved high accuracy: thermocouple 98.9%, moisture sensor 97.4%, level sensor 98.82%, and GPS speed 97.3%, with 100% rule-based output conformity across all 40 scenarios and a mean response time of 0.9314 seconds. Field classification across 3,201 time-series readings yielded 93.22% overall consistency with perfect recall for CRITICAL and WARNING states. Brake pad temperature rose from 35°C to 134°C on downhill roads, supporting the 120°C early warning threshold. Thermocouple reliability dropped to 67.7% under severe vibration due to short-circuit interference, and dashboard performance depends on stable internet connectivity. Research implications – This study advances prior single-parameter approaches through a three-tier classification framework (NORMAL–WARNING–CRITICAL), enabling more comprehensive and robust brake condition monitoring for real-world motorcycle safety applications. Originality – The primary contribution is repositioning the thermocouple from the fluid reservoir to the brake pad surface, enabling more proximal thermal monitoring directly at the friction interface.
