Need brake help PLEASE

I have a 70 charger with manual front dics brakes, afew weeks ago the brakes started grabbing pulling hard to right. Calipers not releaseing I checked with afew guys at the auto parts store and they all said I needed to change my calipers, because they were sticking, Well I did that today and THE NEW ONES STILL STICK!!! It locks up the front I have to open the breeder value to get them to release. Can ANYONE tell me what else to change? Can't drive it like this.....
