The invention discloses an additional brake for an escalator or an automatic pavement; a control part controls a brake boot to move between a non-brake position and a brake position according to a calculation result of a brake deceleration calculating part and a load calculating part; when the brake boot moves from the non-brake position to the brake position, corresponding brake force is given to a main shaft, and friction effect can stop the main shaft from rotation. The additional brake can correspondingly change the brake force according to the load and brake deceleration, thus realizing brake purpose while satisfying brake deceleration requirements, reducing impact, and realizing small brake deceleration for the escalator or automatic pavement.
