Lubricate Loaded Calipers? Brakes dragging intermittently

I don't think I've ever lubed those pins, and have had no problems. Check hemi71's post. Any reason to assume something might be binding? Are these factory or fabbed caliper brackets?

I would CERTAINLY look into clean release at the master. You can remove the cap, "shield" it with the cap or rags, and have someone apply and release the brakes. You should see a "backflow" of fluid up into the reservoir
