why does my brake caliper seize up and turn red? on 2008 Dodge Avenger

I have tried replacing brakes and caliper but it didnt work. My caliper wont release and turns cherry red. What else can I do?

Replace the rubber or 'flex' hose that goes to that caliper! It has collapsed inside, fluid under pressure from mast. cyl. pushes brake pads but cant release as fluid gets trapped holding brake pads against the brake ROTOR heating it to glowing red!
