The invention discloses a method and a device for regulating brake shoe pressure of a train. The technical scheme uses the elastic forces of a spring as braking power of a brake shoe or a brake pad when a train performs brake shoe or brake pad braking, and through compressed air pushing a piston in a cylinder, the elastic force of the spring is regulated, so as to regulate pressure of the brake shoe or the brake pad. The technical scheme greatly simplifies a braking system of an existing train, and greatly improves traffic security performance of an existing vehicle. Even though a train is in a travelling process, all compressed air braking systems have broken down, the device can ensure the train to safely stop operation. The method and the device are advantaged by reliable method and easy implementation, and greatly improve safety reliability of the train. The device is also advantaged by simple structure, easy maintenance, and low manufacturing cost, and is completely compatible to existing trains.
