Lot serialization & full batch traceability
Every brake pad backing plate is laser-etched with part number, batch ID, and production date, linking back to raw material lot numbers, press logs, and final inspection COA reports.
In-House Laboratory & Testing Protocols
Engineering Dynamometer & Material Quality Matrix
Every formulation and production batch undergoes strict in-house laboratory evaluation under SAE, ISO, and ECE R90 international test procedures.
Full-Scale Inertia Dynamometer Testing (AK Master)
Simulates real-vehicle deceleration across 100°C–650°C, verifying friction stability, high-speed sensitivity (up to 200 km/h), and thermal recovery.
