Yes, took the wheel off, and the calipers, all of them. I didn't disconnect the brake lines, but I pulled them from their mounts. Checked and re-greased the pistons and guide bolts. On two calipers, the guide bolts had seized and the caliper wasn't moving. I had to hammer out the offending bolts. New bolts, new grease, all is good now. Advanced Autoparts carries the replacements for everything I needed.
