The present invention has the purpose of providing a brake system and brake control method capable of efficiently supplying negative pressure by an electric vacuum pump and prolonging the pump life span. The brake system is provided with an electric vacuum pump (7) for supplying negative pressure to a brake booster (3), and stops the electric vacuum pump when the level of vacuum in the brake booster exceeds a preset upper limit, or when the continuous operating time of the electric vacuum pump becomes longer than a preset time period, whichever occurs earlier. As a result, the negative pressure supply efficiency of the electric vacuum pump can be raised and the pump life span can be prolonged. |
