Abstract: A braking system for a railway vehicle having bogies which have fixed axles and independent wheels, the braking being of the disk-brake type. Each brake includes multiple disks comprising rotary disks (7) secured to the wheel (2) to be braked and fixed disks (8) secured to the axle (1) carrying the wheel to be braked, braking being obtained by pressing the fixed disks against the rotary disks, the system also including a cooling circuit enabling the heat energy generated by braking to be dissipated, cooling being obtained by a forced flow of fluid through the circuit.
