An elevator system includes an elevator car, at least one elevator drive arranged in an elevator shaft and a support strap, wherein the elevator car is arranged in the elevator shaft for movement via the support strap by the elevator drive. A brake system includes a car braking unit associated with the elevator car and a drive braking unit associated with the elevator drive. The car braking unit and the drive braking unit can together be controlled from a common brake control device. The brake system can be used for new elevator system installations and for retrofitting existing elevator systems.
