The invention relates to hydraulic equipment, in particular to a running and parking integrated high-frequency-response hydraulic control brake system which comprises a brake valve set which comprises a two-position two-way electromagnetic valve, a two-position three-way electromagnetic valve, a proportional valve, a first pressure sensor, a second pressure sensor and a high-pressure oil source. One path of the high-pressure oil source is connected with an inlet of the two-position two-way electromagnetic valve, an outlet of the two-position two-way electromagnetic valve is connected with an inlet of the proportional valve, an outlet of the proportional valve is connected with a first inlet of the two-position three-way electromagnetic valve, and an outlet of the two-position three-way electromagnetic valve is used for being connected with a brake end. The other path of the high-pressure oil source is connected with a second inlet of the two-position three-way electromagnetic valve, the first pressure sensor is used for measuring the oil pressure of the high-pressure oil source and transmitting the oil pressure to the proportional valve controller, and the second pressure sensor is used for measuring the working oil pressure of the two-position three-way electromagnetic valve and transmitting the working oil pressure to the proportional valve controller. The device has the functions of dynamic service braking and power-off parking keeping, and is more reliable and safer during power-off parking.
