Abstract

See full text

A method of tensioning a park brake system of a vehicle includes providing an adjustment mechanism having a nut in threaded engagement with a rod that defines a signal to noise ratio therebetween. The nut is advanced on the rod to remove slack until torque applied to the nut indicates that the park cables include a tension equal to an offset tension level. The nut is then retracted on the rod to introduce slack into the park cables and reduce the tension in the park cables to a target slack tension level. A signal to noise ratio between the nut and the rod is improved so that the cable tension may be predicted by the torque required to turn the nut on the rod, thereby allowing a torque indicating tool to measure the tension in the park cables my measuring the torque required to turn the nut on the rod.
