Abstract
A cable tensioning system for removing slack from a parking brake cable or the like including an improved resettable holdout arrangement for retaining an adjuster ratchet in a spring-biased caged condition during transport and installation of the system in a vehicle. Three embodiments of the invention are characterized, respectively, by the use of an axially displaceable lockout pin that defines an abutment in the path of the adjuster ratchet, a lockout spring having an arm portion adapted to extend into a corresponding notch contained in the periphery of the adjuster ratchet, and a lockout pawl arrangement biased by a lockout spring for cooperation with the ratchet teeth.
