A brake device S comprises a service line 1, an emergency line 3, a main air tank 4, a wheel park air tank 5, and a switching unit 6. The service line 1 allows air for activating a service brake A of the vehicle to pass therethrough. The emergency line 3 allows air for activating an emergency brake C of the vehicle to pass therethrough. The main air tank 4 stores air. The wheel park air tank 5 stores air that is supplied to the emergency line 3. The capacity of the wheel park air tank 5 is smaller than the capacity of the main air tank 4. The switching unit 6 has a valve 62. When a brake pedal B is pressed while the service line 1 is damaged, the valve 62 opens an opening 61 more quickly as the value obtained by subtracting the pressure of air supplied from the wheel park air tank 5 from the pressure of air supplied from the main air tank 4 increases. The opening 61 is configured to cause air flowing in from the emergency line 3 to flow out to the service line 1.
