  • PARKING BRAKE MECHANISM
    Publication number: 20100078274
    Abstract: A parking brake mechanism for an air-actuated disc brake includes an electrically powered actuator, an extensible device drivably connected to the electrically powered actuator and able to extend and retract and be held in place in an extended position to thereby apply a brake, and a resilient device arranged to act on the extensible device and maintain a desired level of force to be applied by the parking brake mechanism in the event of contraction of brake components due to cooling.
    Type: Application
