According to an aspect, there is provided an elevator car parking brake comprising brake pads and an actuator configured to move the brake pads with respect to a guide rail. The elevator car parking brake further comprises levers, each having an associated brake pad; and at least one screw associated with the actuator and rotatably fixed to at least one lever via at least one attaching member. In a braking operation, the actuator is configured to rotate the at least one screw in a first direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move towards the guide rail. In a brake release operation, the actuator is configured to rotate the at least one screw in a second direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move away from the guide rail.
