In need of help I replaced 3 brake calipers on my front passenger side and they keep freezing up what is going on it's a 2011 f250 4x4 6.2 gas

 

Suggest you consider replacing the brake hose to that particular caliper, then bleed caliper to assure all air from hose and caliper is removed.

 

Consider replacing guide pins are also a culprit

 

Good point regarding guide pins.
A little FYI,,,,,,,,,,,,,,many times they can be cleaned and lubricated. Be sure to use only synthetic grease which is not harmful to the rubber boots and can better with stand the heat generated at the caliper.
