The safety apparatus for a brake of a vehicle includes a first line and a second line. The first line includes an exhaust manifold, an engine, an intake manifold, a check valve, a vacuum hose, a vacuum switch, a booster, a check valve, a vacuum hose, a negative connection portion, a vacuum switch and a brake booster, and the second line includes a vacuum hose, a check valve, a booster, a check value, a vacuum hose and a vacuum pump, which are connected to the negative connection portion. The 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.
