MANAGE WHAT
YOU CAN'T MEASURE
Brake pad temperature is one of the most critical and least monitored parameters in performance driving. Pads operating above their thermal threshold experience rapid degradation, fade, and failure — but most drivers have no real-time visibility into what's happening at the rotor.
TrackTechPro was built to fix that. A custom PCB system with temperature sensors at each corner, a real-time LCD display, and data logging — designed, built, and installed from scratch.
This wasn't a kit. Every hardware decision — PCB layout, sensor selection, power management, display interface — was made and executed independently.
- Arduino Nano — main controller on breadboard
- Thermocouple sensors at brake corners
- IMU — accelerometer + gyroscope for cornering data
- LCD display — real-time temp readout
- 12V vehicle power input with regulation
- Custom wiring harness to each corner
- Arduino C/C++ sketch
- Real-time multi-sensor polling loop
- Temperature threshold logic and alerts
- IMU data read and cornering event detection
- Brake temp + cornering correlation logic
- LCD display rendering and refresh
- Sensor routing to all four corners
- Chassis-mounted PCB enclosure
- Display positioned in driver sightline
- Fused 12V power tap from vehicle
- Vibration-isolated mounting
- Weatherproofed sensor connections
REAL COACHING DATA
Brake temperature alone tells you that something is happening — it doesn't tell you why. Adding an IMU to the system was the design decision that turned a temperature logger into an actual driver coaching tool.
The IMU measures lateral G-force in real time. When high brake temperatures coincide with high lateral G — the car is cornering — that's a trail-braking event. When it happens repeatedly at the same corner, that's a driver habit. A problem the driver may not even know they have.
This is the kind of systems-level thinking I apply to every problem: what data do I actually need to answer the real question, and how do I build the system that captures it?
