Beschreibung
Zusammenfassung:	An elevator safety brake for stopping an elevator car is provided with a brake shoe having a carbon-carbon composite friction surface for contacting an elevator guide rail surface to provide a stopping force. The friction surface of the brake formed from the carbon-carbon composite exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.
