Abstract: A double brake chamber is provided to reduce the manufacture cost and improve repair and maintenance efficiency by implementing parking and service brake through control of the tension of the spring and air pressure in one chamber. A double brake chamber comprises a housing(10) in which a service brake line(11) and a parking brake line(12) are provided, a diaphragm(20) located in the center inside the housing and moving back and forth when air pressure is applied, a piston rod(30) which is formed to penetrate and fixed to the diaphragm, and a spring(40) which is formed behind the diaphragm in order to vary the diaphragm with the supply of air pressure.
