An elevator brake failed during use. Failure analysis was performed on magnetic sleeve of the elevator brake. The metallographic microstructure and SEM morphology of the elevator brake magnetic sleeve were investigated based on the optical microscope and scanning electron microscope analysis. The results showed that the entrance of foreign materials caused the extrusion wear to local area of the inner surface of the magnetic sleeve.
