1. A braking system for a vertical stacking panel door, comprising:
a housing, wherein the housing comprises angled slots;
a first rod coupled to the angled slots of the housing in an interior volume of the housing;
a strap comprising a loop on an end of the strap, wherein the strap is coupled to the first rod via the loop;
a second rod movably coupled to the housing, wherein the second rod is to engage a linear ratchet when moved from a disengaged position to an engaged position; and
a torsion spring, wherein an end of the torsion spring interacts with the second rod, wherein tension from the strap moves the first rod within the angled slots and causes the torsion spring to rotate in a first rotational direction to cause the second rod to move into the disengaged position, and the torsion spring rotates in a second rotational direction to allow the first rod to move within the angled slots of the housing such that the end of the torsion spring and the movement of the first rod cause the second rod to move into the engaged position when tension is lost on the strap.
