A notification device and a notification method to announce a current operation mode of an elevator, especially a maintenance or inspection mode, is provided for the elevator that executes the notification method. The elevator includes a control assembly allocated outside of a shaft of the elevator, wherein the notification device is electrically connected or communicates with the control assembly. The notification device includes a display that displays information depending on the status of a lock of the control assembly, wherein the display is off or displays a predetermined first information when the lock is locked, and the display is on and displays a predetermined second information when the lock is unlocked.

According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.
