A method for controlling movement of an elevator car, wherein the elevator comprises an elevator car arranged to travel vertically in a hoistway along at least one guide rail, and a suspension roping for suspending the car during its travel in the hoistway, the elevator car comprising an openable door in a doorway leading to the inside space of the elevator car and a park brake for holding the elevator car immovable at a landing (L0-L3), which park brake is mounted on the car, the method comprising driving the elevator car vertically to a landing (L0, L1, L2 or L3); and activating at least one brake mounted on the car; and holding the car immovable at the landing (L0, L1, L2 or L3) by means of the at least one brake mounted on the car, said holding comprising compressing at least one guide rail by compression members (6a, 6b) of the at least one brake with a first compression force; and opening a door for allowing loading and/or unloading the elevator car; maintaining a door open for allowing loading and/or unloading the elevator car while the car is held immovable; and starting closing movement of said door; characterized in that the method comprises after said starting closing movement of said door (d): relieving the at least one brake for allowing the elevator car to start to move vertically, said relieving comprising reducing the compression force of the at least one brake, to be smaller than said first compression force, such that the compression members (6a, 6b) start sliding vertically against the guide rail; and maintaining compression with smaller compression force than said first compression force, allowing the compression members (6a, 6b) continue to slide vertically against the guide rail; and thereafter removing the compression. driving the elevator car vertically to a landing (L0, L1, L2 or L3); and activating at least one brake mounted on the car; and holding the car immovable at the landing (L0, L1, L2 or L3) by means of the at least one brake mounted on the car, said holding comprising compressing at least one guide rail by compression members (6a, 6b) of the at least one brake with a first compression force; and opening a door for allowing loading and/or unloading the elevator car; maintaining a door open for allowing loading and/or unloading the elevator car while the car is held immovable; and starting closing movement of said door; characterized in that the method comprises after said starting closing movement of said door (d): relieving the at least one brake for allowing the elevator car to start to move vertically, said relieving comprising reducing the compression force of the at least one brake, to be smaller than said first compression force, such that the compression members (6a, 6b) start sliding vertically against the guide rail; and maintaining compression with smaller compression force than said first compression force, allowing the compression members (6a, 6b) continue to slide vertically against the guide rail; and thereafter removing the compression. relieving the at least one brake for allowing the elevator car to start to move vertically, said relieving comprising reducing the compression force of the at least one brake, to be smaller than said first compression force, such that the compression members (6a, 6b) start sliding vertically against the guide rail; and maintaining compression with smaller compression force than said first compression force, allowing the compression members (6a, 6b) continue to slide vertically against the guide rail; and thereafter removing the compression.
