If the front brakes are locking up you need to open the bleeder on a caliper to see if the wheel can then be turned. If you can now turn it then you may have bad front brake lines that hook up to the calipers. If the caliper still does not release when you open the bleeder then the problem is with the caliper piston or the slides are seized.
