A safety apparatus for a brake of a vehicle is provided. The safety apparatus for a brake of a vehicle includes a first line and a second line. The first line includes an exhaust manifold 1, an engine 2, an intake manifold 3, a check valve 4, a vacuum hose 5, a vacuum switch 6, a booster 7, a check valve 8, a vacuum hose 9, a negative connection portion 10, a vacuum switch 11 and a brake booster 12, and the second line includes a vacuum hose 15, a check valve 16, a booster 17, a check value 18, a vacuum hose 19 and a vacuum pump 20, which are connected to the negative connection portion 10. The safety apparatus can isolate a supply of electric power to a fuel motor to stop starting of the engine when the brake booster lacks a vacuum because of a deterioration of a performance of an auxiliary vacuum pump, and enable the brake to normally operate so as to prevent an accident even though a sudden acceleration occurs or the engine suddenly stops. |
