Next time this happens, open the bleeder screw on that caliper, then see if the brake releases. If it does not, suspect the caliper. If it does release, the brake fluid is being trapped and can't flow back to the master cylinder freely. Do the test again by loosening the steel line at the master cylinder. You're looking for the first place the fluid pressure releases.
