An elevator brake wear detection method, an elevator brake wear detection device and an elevator brake. The elevator brake includes a fixed part with an electromagnetic member and a moving part with a friction member; in a first state, the elevator brake drives the moving part to move toward an elevator power device and contact the elevator power device through the friction member to provide a braking force to stop an elevator car, and in a second state, the elevator brake provides an electromagnetic force through the electromagnetic member to disengage the friction member from the contact with the elevator power device.
