Brake application at the wheel end begins with air pressure, and the MGM Brakes Air Brake Chamber converts that pressure into mechanical force. Inside the chamber, compressed air pushes against a diaphragm, which moves the pushrod to apply braking force. Combination chambers handle both service and spring brake functions within one unit. This setup allows braking to occur during normal operation and also provides parking or emergency braking capability. Force transfer remains consistent with the MGM Brakes MJS3628ET060 managing air-to-mechanical conversion.
