The invention relates to a combined service brake cylinder and spring brake cylinder (1) for operating a service brake and a parking brake, comprising a spring brake cylinder (4) having a spring brake cylinder housing (11), a spring brake piston (10) and at least one accumulator spring (3), the spring brake piston (10) is guided in a displaceable manner on a radially inner circumferential surface of the spring brake cylinder housing (11), and wherein the spring brake piston (10) is guided in a displaceable manner on a radially outer circumferential surface of the spring brake cylinder housing (11). The spring brake piston (10) and the spring brake cylinder housing (11) delimit a spring brake chamber (15) which can be pressurized by parking brake pressure; a separate service brake cylinder (6) and a service brake piston (18), at least the service brake piston (18) delimiting a service brake chamber (19) which can be pressurized by a service brake pressure, c) the service brake cylinder (6) is arranged in the spring brake cylinder housing (11) as viewed in the radial direction, and the service brake piston (18) is connected to a service brake piston rod (22). The service brake cylinder (6) is pot-shaped and has a cylindrical wall portion (37) extending parallel into the spring brake cylinder housing (11) and a first bottom portion (23a) connected to the cylindrical wall portion (37), the service brake piston (18) being displaceably guided directly on a radially inner circumferential surface of the cylindrical wall portion (37) of the service brake cylinder (6), and wherein the first bottom portion (23a) of the service brake cylinder (6) is provided with a central opening through which the service brake piston rod (22) protrudes. Alternatively, the service brake cylinder (6) has a second bottom portion (23b) connected to the cylindrical wall portion (37), the service brake piston (18) being displaceably guided directly on a radially inner circumferential surface of the cylindrical wall portion (37) of the service brake cylinder (6), and wherein the service brake piston (18) is displaceably guided directly on a radially outer circumferential surface of the cylindrical wall portion (37) of the service brake cylinder (6). The second bottom portion (23b) of the service brake cylinder (6) forms a bottom or cover of the spring brake cylinder housing (11).
