The present invention provides a parking brake tensioning apparatus, method, and system. Generally described, the device is for adjusting the tension cable of a parking brake in a vehicle. The device has an inner housing for receiving the handle of the parking brake. Also, the device has a deformable member attached to the housing, and is preloaded with a predetermined load. The device further has a force probe, or rod, having a first end connected to the deformable member and a second end in contact with a component of the vehicle. In addition, the device has a switch for generating a control signal when a predefined force value is applied to the deformable member by adjusting the tension of the tension cable through an adjustment tool. Furthermore, the device has a relay for transmitting the control signal to the adjustment tool once the predefined force value is reached, thus disabling the adjustment tool. Other embodiments are also claimed and described.
