safety brake
Halts runaway motion
A safety brake is a braking mechanism designed to engage automatically if the primary brake fails or in emergency situations.
Elevators have safety brakes that grip the guide rails if the cable breaks.
Vehicles may have safety brakes that activate when the main hydraulic system loses pressure.
The term overlaps with emergency brake and parking brake, though safety brake emphasizes the fail-safe function rather than routine use.
