Could this be caused by air in the system/old fluid or even the piston itself is not Clean causing it 2 stick or even not allowing the piston to push the pads to the disc. My advice would be strip clean and grease the piston along with pad runners and renewing fluid and bleed the system to eliminate all off the above.
