Front Brake Stiff

I'm Completely Stumped-!!
Ok Working on a friends 98 FLTRI (Road King). Duo Front brake,
cleaned out brake system,
New washers on banjo bolts,
Replaced the Caliper seals and inspected the pistons,
rebuild the Master,
Checked the rotors for warp-age (none),
Bled the brakes
Lever stiff (only about 1/8-1/4 inch movement before grab)
Master cylinder not showing that the fluid is flowing back into it.
The Calipers are releasing from rotor.
Double and triple checked to make sure all seals and rebuilt Master
where correct.
Anybody got any Ideas what it might be or had this problem. Before I tear it completely apart for a fourth time.
