Are the pads "cheap" or very metallic ?
Binding brakes means the pistons are not returning properly from the disc-face, or into the caliper, once you've let the brakes off.
This could be the pads sticking on the pins, but if you've cleaned and lubricated these, then I'd suggest the pistons are the problem - probably built up dried grunge around them (might have got into the seals as well). Personally, I'd do a proper caliper overhaul, taking the pistons out and cleaning the up (fitting new seals as well) - it's easy, doesn't take too long and doesn't cost too much.
