To fix a broken Albrecht JACK PCL BRACE that has lost tension on both sides, follow these steps:

1. Set the levers of both hinges to the "off" position.
2. Deactivate the spring tension by pushing the lower leg shell to posterior. Place your hands under the hinge bar and your thumbs on the pressure blocks attached to the lower leg shell.
3. Push the shell posterior using your thumbs to deactivate the anterior-directed spring force.

If the brace remains non-functional after deactivating and resetting the tension, further technical inspection or part replacement may be necessary.
