I'm tryig to get my Wilwoods buttoned up...
I would get the front on Jack Stands.Disconnect the brake rod.See if the front brakes still have drag.If they spin freely rod adjustment problem.If not check the way the calipers are mounted make sure they are mounted correctly and nothing is binding.As a last resort disconnect the front brake hose at frame and rubber hose.What trying to accomplish to see if your problem is mechanical or hydraulical.Hopefully this makes sense and helps you out.
