Bleed your fluid, there may be a restriction (crap) in it, that stops it from flowing back. Or maybe, your master cylinder piston is not returning.

Is it doing it on all wheels or just one?

Any chance the master cylinder you are using is setup to run a drum brake up front too? Drum brakes require some residual pressure on the line when you let off the pedal. This is to help keep the shoes close to the drum even though the springs want to retract the shoes completely. The residual pressure kept on drums is 10psi. Disc brakes require much less residual pressure (~2psi), but if you have the drum type valve on them they won't retract as the runout on the rotor is not enough to push the pads away.

Are you certain that the pushrod from the brake pedal is retracting all the way?

I've had them fall on the lip of the plunger of the mastercylinder and heat my newly installed front discs up really quick which made it where they wouldn't let off the brake.
