Abstract
The invention provides an emergency brake apparatus for a vehicle which can brake both of front and rear tire wheels of a vehicle by using an oil pressure, at an emergency time. For this purpose, a pressure oil of a hydraulic power source is changed to a pilot oil pressure which is reduced from a high pressure to a low pressure in correspondence to an operation amount of an emergency brake valve () operated at the emergency time, and this pressure is output to a relay valve (). The pressure oil of the hydraulic power source is increased in an inverse proportional manner from a low pressure to a high pressure in correspondence to the pilot oil pressure, and this pressure is output to a front tire wheel brake (), thereby urgently braking the front tire wheel.
