front discs locking up

I've been having the same problem with my K-H front discs, and would like to thank you all for your helpful replies. It did improve somewhat when I squirted the caliper, pads and rotor down with brake cleaner, but there's still too much drag as far as I am concerned. I think I am next going to try removing my calipers and cleaning the "ways", as 2 Darts suggested.
