PURPOSE: An injecting apparatus of brake oil for an HCU(Hydraulic Control Unit) is provided to inject brake oil into the HCU automatically and to measure injected volume. CONSTITUTION: An injecting apparatus of brake oil for an HCU(Hydraulic Control Unit,2) includes a vacuum device(20); a low pressure injecting device(30); a high pressure injecting device(40) and an air supply device(10). The vacuum device connects a vacuum line(22) into the HCU to inject oil. The HCU is installed to a manifold(4). Therein, residual oil of the HCU is exhausted. The low pressure injecting device injects most of decided volume of oil by connecting a low pressure line(31) into the HCU. The high pressure injecting device injects oil with measuring injecting oil. A high pressure line(41) is connected from the high pressure device into the HCU. The air supply device supplies air to the low pressure injecting device and the high pressure injecting device selectively.
