front discs locking up

more info is needed to help. Are calipers free, do you have a power booster, does car have headers near brake lines, how much drag on the rotors before you take a ride ? This is an easy problem if you get all things are checked. make sure brake fluid is not contaminated. one strange problem can be the rubber line have an implosion (that means the fluid goes to the wheel from pedal pressure by your foot and it can't return at normal flow) this is a problem when the lines are ancient. Good Luck
both calipers are free and working fine, I can compress them easily and they seem to work fine. no power booster just manual breaks and no headers..yet. just the (as I call them over slung manifolds). gonna flush the system and change the flex hoses as everything else is new (at the wheel). there dosent seem to be any drag when they are cool. I was thinking the flex lines as well , they don't seem to be weather cracked but they are old (probably 6 - 8 years)

thanks everyone for the sugestions
