The clutch and brakes do not share a master cylinder. If they did and the clutch slave cylinder sprung a leak, you'd lose your brakes too.
What you're describing is typical of the brake fluid contaminated with a petroleum product, but there are other causes of dragging brakes. Stop on a slight incline, then release the brake pedal and see if the car creeps downhill on its own. If it does not, or if you can't push the car by hand, we have to figure out where the brake fluid is being trapped. A parking brake cable could also be rusted in the partially-applied position. Ford has a lot of trouble with sticking cables.
