The cable, or rather the quadrant is self adjusting, the normal problem with them is they can strip the teeth on the adjuster, there are different amount of teeth on the auto adjusters on different fords, not sure how many on cos quadrant.
The easy way to get it to reset and self adjust is lift the pedal, then with your thumb push the quadrant forwards at the top, this will take off the adjustment so when pedal is let go and then pressed a few times it wil click away self adjusting.
