Abstract

A hydraulic brake system for a vehicle, including: a wheel brake device configured to generate a braking force based on a pressure of a working fluid; a first brake system including a high-pressure source device including an accumulator and a first pump device that is driven intermittently such that a pressure of the working fluid in the accumulator is not lower than a set lower limit pressure and not higher than a set upper limit pressure; a second brake system including a second pump device; and a main power source that supplies electricity to the first and second brake systems, wherein the hydraulic brake system includes an auxiliary power source that supplies electricity to the first brake system when a failure occurs in the main power source, and wherein the first pump device is continuously driven when the failure occurs irrespective of the pressure in the accumulator.
