Some elevators, maybe up to 5 landings may be hydraulically powered. No brake mechanism there. Noises from pumping equipment is limited to a hallway just outside the equipment room or that room can be within another room which significantly reduces outside noise, or the equipment room faces the building’s exterior so nearly all noise is outside the building.
Traction machines which use the traditional penthouse for all equipment (room is on the roof) are somewhat insulated from the building’s interior.
MRL’s on the other hand have their hoisting motors exposed fully at the top of the shaft so this particular noise from the brake opening and closing can be heard from outside which is your case. Also brake adjustment can be within machine specs, but are louder from one machine to another simply because of mechanical operation. To understand brake operation better, search out on YouTube “KONE MRL brake operation” and you’ll see the machine and hear your exact distinct brake noise. Under normal wear, that brake and friction shoes will last for quite awhile.

Good luck on the outcome!
