Abstract
A park brake assembly (20) provides a hand or foot operated park brake actuator (30) connected to a drive reel (48) via a flexible motion transmitting core element (68). The drive reel (48) is connected to an isolator crank (56) via a lost motion connection (46). The isolator crank (56) is operatively connected to a control crank (76) which, in turn, directly actuates the park brake (26). The control crank (76) includes a lock sector (102) which coacts with a pawl (104) to selectively maintain the park brake (26) in a brake applied condition. When in the brake applied condition, the lost motion connection (46) allows the drive reel (48) to return to an unactuated position thereby eliminating all stresses from the actuator (30). The pawl (104) includes an elongated slot (108) and a trip spring (110) which coact to alternatively ratchet the pawl (104) against the lock sector (102) and then to disengage the pawl (104) from the lock sector (102) without requiring an independent release mechanism.
