The invention discloses a pressure output control system for hydraulic braking. The pressure output control system comprises a three-way pressure reducing assembly and a three-way reversing valve assembly. The input end of the three-way pressure reducing assembly is connected with an input pipeline, and the output end of the pressure reducing assembly is connected with the input end of the reversing valve assembly through a transition pipeline. The other output end of the three-way pressure reducing assembly is connected to an oil tank through a return pipeline I; the output end of the three-way reversing valve assembly is connected to a connector A through an output pipeline, and the connector A is used for being connected with a brake clamp. And the other output end of the three-way reversing valve assembly is connected to the oil tank through a return pipeline II. The invention further provides a hydraulic braking system comprising the pressure output control system; and the hydraulic braking system is simple in overall structure, high in control precision and beneficial for guaranteeing stable operation of the braking clamp.
