  • Patent number: 9347482
    Abstract: 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.

  • Patent number: 8904618
    Abstract: A method of tensioning park cables of a park brake system includes positioning a tension indicating device between an adjuster and an adjusting nut when the park brake system is disposed in a slack position. The tension indicating device includes an axial spacing length between the adjuster and the adjusting nut that is equal to a desired adjustment distance of the park cables when the park brake system is disposed in the slack position. The adjusting nut is then tightened until the tension indicating device indicates that the park cables include a tension equal to a target tension level of the park cables when the park brake system is disposed in an applied position. The tension indicating device is then removed from between the adjuster and the adjusting nut, thereby introducing slack into the park cables that is equal to the axial length of the tension indicating device.
