Brake system and vehicle

The utility model discloses a braking system and a vehicle. The braking system comprises a liquid storage tank, a braking device and a braking device, a wheel cylinder; the main pressure relief oil way is connected with the liquid storage tank and the wheel cylinder, and the main pressure relief oil way controls whether oil in the wheel cylinder flows back to the liquid storage tank or not. The standby pressure relief oil way is connected with the liquid storage tank and the wheel cylinder, the standby pressure relief oil way is connected with the main pressure relief oil way in parallel, and the standby pressure relief oil way controls whether oil in the wheel cylinder flows back to the liquid storage tank or not. Therefore, pressure relief can be performed through the main pressure relief oil way, pressure relief can also be performed through the standby pressure relief oil way after the main pressure relief oil way loses efficacy, and opening and closing of pressure relief at the wheel cylinder can be cont
