The air brake chamber is needed higher sealing performance and durability for the safety and confidential operation, especially, in brake systems of commercial vehicle. For higher sealing, we applied new clamping technique differentiated methods of other global manufacturers. And we developed the power spring and spring guide made from light engineering plastic with high durability in repeated condition. We also have achieved the basic performance test like sealing test in compressed air and various environment tests in dust and salty water for new manufactured air brake chambers. As a result, the air brake chamber applied light weight and high durable power spring is satisfied all demand specification conditions for commercial vehicle
