2006 Chevrolet Equinox - new caliper didn't clear ABS light

Replaced caliper twice,not releasing brake,abs light on ,brakes grab as I drive

That’s a problem, take it to a mechanic that can read ABS error codes.

May be a separate problem. The brake hose to that corner may have failed internally and is acting like a check valve. Replace it and see if it goes away. If it does replace ALL of the rubber lines as this WILL happen again. GM made crappy brake hoses.
