  • Brake device 1 to train reduced components and space-saving. Because the transmission device 9, the leaf springs 16, the hydraulic chamber 7 and the annular piston are completely accommodated in the receiving space of the brake disc 5, it is possible to design the braking device 1 to be particularly narrow and to position it next to the wheel 51 on the wheel axle 55.
