good morning and thank you for inquiring withJustAnswer. As you stated, it should be pretty straight forward, though sometimes there are a few things that could cause the brakes to 'grab' or 'drag' afetr releasing the pedal. The first and foremost thing that i rarely see when a brake concern comes in is the presence of lubrication on the caliper slides,pins and caliper brackets. These pad and pin mating surfaces should have a coating of brake dieloectric grease on them (Ford part number XG-3-A), and the lack of lubrication could be the cause since there is a metal onb metal contact which needs to be able to slide freely. The other thing i have seen quite often as well is after a brake job, the calipers are installed 360 off, causing a kink in the brake hose, which restricts brake fluid to return and in turn could cause nbrakes to not fully release. If those items are covered then it could be that there is a fault internal to the calipers that would warrant caliper replacement. below i have posted the procedure out of the shop refference for you to familiarise
CAUTION: Do not pry in caliper sight hole to retract pistons as this can damage the pistons and boots.
CAUTION: When removing the disc brake caliper, never allow it to hang from the brake hose. Provide a suitable support.
CAUTION: Do not allow grease, oil, brake fluid or other contaminants to contact the pad lining material. Do not install contaminated pads.
NOTE: Install all hardware supplied with pad kits. Lubricate all metal to metal contact surfaces with XG-3 grease.
NOTE: Use a wood block or used pad to protect pistons and boots.
CAUTION: Use care not to damage the bleeder screw or front brake disc shield.
I hope my assistance helped you and resolved your concern, if you need further assistance please ask.
