Answer
Hello Charlie.
Replace the flexable hoses from the frame to the steering knuckle. They deteriorate on the inside, and form plugs, preventing the release of pressure. You can verify that by opening the bleed screws, and see if pressure is trapped, holding the brake applied.

I would ask if you rebuilt the caliper pistons, or did you just squeeze the pistons back into the caliper bores, where there may be rust and crud buildup, preventing the piston from moving freely.
