I assume you pumped them up?

Yes. I pumped the lever 5-7 times, held it down, opened the bleeder valve, a little fluid came out each time. I tightened the valve then released the lever and pumped again.I repeated the process 3 or 4 times topped it up with fluid and no brakes at all.

I use a Mity-Vac to pull brake fluid thru the system. Not needed though, just makes it easier. Are you sure the piston is not stuck/corroded? I usually have to pull the pistons out, polish them with either super fine steel wool or brillo pad, replace the piston seals and checking the grooves the seals sit in before installing them. Have found corrosion in the caliper grooves that the seals sit in! VERY annoying. I ride year round and de-icer has been on my scooter several times. No amount of rinsing will save a front caliper from corrosion. Just rebuild when pads are due.
