PURPOSE: An electro-mechanical brake system with fail-safe function is provided to pull over the vehicle safely by performing fail-safe function for the engine brake with controlling rpm and torque of an engine, and to prevent collision by displaying the emergency state with operating an emergency lamp by receiving a driving signal from an electro-mechanical brake control unit in failure of the brake system from wrong operation of a pedal stroke displacement sensor during traveling at high speed. CONSTITUTION: An electro-mechanical brake system comprises a pedal stroke displacement sensor(2), a brake lamp switch(14), an electro-mechanical brake control unit(12), an engine control unit(13), an emergency lamp(15) and an actuator. The electro-mechanical brake control unit performs fail-safe function by receiving signals from the pedal stroke displacement sensor and the brake lamp switch in abnormally operating the electro-mechanical brake system from wrong operation of the pedal stroke displacement sensor during high speed traveling, and the engine control unit functions as the engine brake by controlling engine rpm and engine torque of a vehicle with receiving the control signal from the electro-mechanical brake control unit. The emergency lamp displays the emergency state of the vehicle by receiving the driving signal from the electro-mechanical brake control unit.
