If it does , the problem is caliper related
Ive heard of fiesta calipers not sitting square on the back of the mini hub , making the pads sitting out of true on the disc
That would give those symptoms

Another possibility that i have seen and suffered myself is that just using one method may not be capable of removing any trapped air.
Try using an Easi bleed and the manual pumping the brakes at the same time.
I suffered horrendous issues with my RS2000 brakes after i overhauled the master cylinder. I used an easi bleed and the front would never lock up, only the rears. As a last ditch attempt i did both methods at the same time and boom sorted.
Now a friend of mine had the same sort of issues with his mini van. Poor brakes, foot to the floor etc etc etc. He was just using an Easi bleed. So i mentioned what i had previously did and it worked for him. Again this was a rebuilt master cylinder and air was trapped in it.

Just to ad, when bleeding the rear brakes make sure the bleed screw(s) are open before the pedal is pushed down. If the pedal is pushed down with the bleed screws still closed, the line pressure can lock-off the pressure relief valve and prevent fluid/air from escaping.

That's a great point. I had this problem with mine some years ago. I ended up using one of the bleed kits which worked with a tube from the bleed nipple to a non return valve submerged in brake fluid in a jar. I open the bleed nipple and pumped the pedal, It sorted it straight away.

Loads of good advice, but be methodical or you'll be chasing yourself round in circles. Start at the master and devise a means of isolating the rest of the system as you work outwards. Some crimped/soldered over pipe stubs in unions will do.
