The invention relates to the technical field of spaceflight test piece recovery and particularly discloses a graded loading low-overshoot braking recovery system and a recovery method thereof. Braking gas sources in the braking recovery system include a high-pressure braking gas source and a low-pressure braking gas source, wherein the high-pressure braking gas source is connected with a high-pressure pipeline and is used for providing high braking pressure for the high-pressure pipeline; the low-pressure braking gas source is connected with a low-pressure pipeline and is used for providing low braking pressure for the low-pressure pipeline; and the rear section of the low-pressure pipeline is connected with a braking device after communicating with the rear section of the high-pressure pipeline, the front section of the low-pressure pipeline is provided with a low-pressure electromagnetic valve, and the front section of the high-pressure pipeline is provided with a high-pressure electromagnetic valve.
