According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.

Disclosed is a brake assembly for an elevator system, having: a housing defining a housing cavity, a housing forward end with a forward end opening into the housing cavity, and a housing aft end; a first magnet disposed in the housing cavity, near the forward end opening; a second magnet disposed in the housing cavity, between the first magnet and the housing aft end, and wherein the second magnet is configured to: reduce attraction between itself and the first magnet, whereby the first magnet moves at least partially through the forward end opening to engage a guide rail that is metallic, thereby preventing vertical movement of the first magnet of the brake assembly, when magnetically connected to the rail, relative to the housing; and attract the first magnet to draw the first magnet into the housing cavity.

A method and brake monitoring device check a current functional state of a brake for an elevator installation traction sheave. The brake has a stationary part and a rotatable part rotationally fixedly coupled to the sheave. A braking mechanism has a displaceable braking element, a biasing mechanism and a release mechanism arranged on the stationary part. The biasing mechanism mechanically biases the braking element with an elastic biasing force toward a braking configuration. The release mechanism has an electrical actuator producing a force acting on the braking element and counteracting the elastic biasing force. The method includes: varying electrical power to the actuator; measuring a release power value that, when exceeded, causes the braking element to switch between the braking configuration and a released configuration; comparing the release power value with a predetermined reference power value; and determining the current functional state of the brake based the comparison result.
