An elevator includes a car and a counterweight suspended on hoisting ropes which are driven by a drive machine. The counterweight has a first side facing the elevator car path and a second side opposite to the car path. The counterweight includes at least one connecting passage between the first and second side of the counterweight. With this solution, air pressure built between the car and the counterweight when passing in the elevator shaft is reduced and the travel comfort is improved.

Elevator

In a method for renewing a braking force of a hoisting machine, a brake pad of a brake of the hoisting machine is pressed against a braking surface of a rotating part of the hoisting machine, and the braking surface is moved in relation to the brake pad pressed against the braking surface by resisting the friction force between the braking surface and the brake pad.
