The invention relates to the field of aircraft assembly stage hydraulic detection, and concretely relates to a method for checking sealing performance and working performance of an assembly-stage hydraulic system. The system comprises a system I and a system II. The method comprises the following specific steps: S1; releasing the pressure; s2; checking the sealing performance of the system; S3; checking the correctness of brake connection of the system I; S4; checking the correctness of brake connection of the system II; S5; releasing the operation of an emergency brake handle; S6; relieving left and right main brake pedal control; S7; checking the sealing performance of a refueling probe; S8; checking the sealing performance of an actuator cylinder; S9; checking the brake non-working performance of a front cabin; S10; checking the non-working performance of the emergency brake of the front cabin; S11; determining valve performance and connection correctness; and S12; checking the sealing performance of a front wheel turning fuel supply pipeline and the correctness of pipeline connection. The sealing performance and correctness of conduit connection are comprehensively checked, thesafety of power supply and pressure supply of equipment is ensured, and reasonable design method is selected, so the working efficiency is improved, and the checking cost is reduced.
