This invention relates to a high-temperature resistant, self-recovering railway brake pad, belonging to the technical field of railway braking devices. It includes a clamping plate, in which connecting posts are rotatably mounted within multiple equidistant circular grooves on the front side of the clamping plate. Mounting plates are fixed to the front of the connecting posts. Buffer adjustment components are provided between the mounting plates and the clamping plate. Brake pads are fitted and slidably mounted within the grooves on the front side of the mounting plates.
