The invention discloses an auxiliary steering brake valve, belongs to the field of brake-steering systems, and solves the problems that an existing auxiliary brake valve is large in occupied space and insufficient in brake oil supply amount of a high-power machine type. The valve comprises a main valve body, a left push rod assembly, a right push rod assembly, the main valve body, a left reversing valve set, a right reversing valve set and a brake valve set are arranged on the main valve body, a left valve cavity, a middle valve cavity and a right valve cavity which are mutually independent and isolated from the outside are formed in the main valve body, and the left valve cavity is provided with the left reversing valve set capable of sliding in the axial direction. The middle valve cavity is provided with a brake valve set capable of sliding in the axial direction, the right valve cavity is provided with a right reversing valve set capable of sliding in the axial direction, and the left reversing valve set and the brake valve set are jointly connected with a left push rod assembly used for driving the left reversing valve set and the brake valve set to move. The auxiliary steering brake valve is small in occupied space, high in brake output pressure, large in generated brake torque, capable of guaranteeing the brake effect and capable of being used on large-tonnage hydraulic brake vehicle models.
