The 4CTPB‑3‑4 Plate Brake Tester is a professional vehicle inspection device designed to test the braking force of various types of vehicles, including passenger cars and light commercial vehicles. It features a four-plate configuration that allows for independent testing of all four wheels, providing highly accurate and reliable measurements. With a maximum axle load capacity of 3000kg and a brake force measurement range up to 10kN, it ensures compliance with national and international standards such as GB21861. The ultra-flat plate design allows vehicles to pass over at speeds of 5–15 km/h, closely simulating real-world braking conditions. This equipment offers easy installation with minimal ground preparation, modular structure for flexible layout, and compatibility with other vehicle testing systems like side-slip testers and emission analyzers. Equipped with high-precision sensors and intelligent data collection software, the 4CTPB‑3‑4 brake tester is an ideal solution for vehicle inspection stations, repair workshops, and automotive testing facilities seeking comprehensive and efficient brake performance analysis.
