The invention relates to the technical field of heavy engineering vehicles, in particular to a brake control valve set and a hydraulic brake system of a heavy transport vehicle. The brake control valve set comprises a first oil way, an external control type pressure reducing valve, an electromagnetic proportional overflow valve and a filtering oil way set, a hydraulic oil source connector, an energy accumulator connector and a hydraulic oil outlet are formed in the first oil way, the external control type pressure reducing valve is arranged on the first oil way, and the electromagnetic proportional overflow valve is arranged on the energy accumulator connector. The electromagnetic proportional overflow valve is connected with the external control type pressure reducing valve, the filtering oil way set comprises a filter, an oil inlet filtering oil way and an oil return filtering oil way, and the oil inlet filtering oil way and the oil return filtering oil way are connected with the first oil way. The filter is used for filtering hydraulic oil in the oil inlet filtering oil way and the oil return filtering oil way. According to the technical scheme, under the background of large flow, the filtering oil way can filter hydraulic oil, so that the service life of the device is prolonged, and the pressure of the large flow can be buffered.
