replacement part needed when the left front brake will not completely release. on 2000 Mercury Villager

Already replaced calipers and pads.

Asked by for the 2000 Mercury Villager
Check the brake hoses for restrictions.with the van raised up pull the wheel off(If I remember correctly the villager is front wheel drive so it would be easier with both front wheels up and have it in neutral)(PARKING BRAKE APPLIED). pump the brakes and make sure you can't spin the front left rotor , then open the caliper bleed screw and see if this releases it .If so then you likely have a bad hose to that caliper.It may look fine on the outside , the damage would be on the inside.
