I have replaced my calipers twice and the front driver side is stuck again ,they were done correctly in pairs so any advice would  be appreciated

Where did you buy the calipers?

Did they come with new mount brackets and slide bolts?

Something else too check. Check your brake hoses. They, with age can break down internally and act like a check valve giving the same symptom as a stuck caliper. easy way to check is to pull the wheels, pump up the brakes and check to see if it is stuck. If stuck open the bleeder and if it frees up it is the hose. Caliper slides can also stick.
