If anyone should experience this with a honda -acura, the easiest solution is to replace the caliper bracket. Expensive! Another way to remove the slider pin is to drill a small hole opposite the threaded side and soak with penetrant from the back as well as the front and slowly wiggle and pull. It may take a while after letting it soak. When the slider finally comes out, use silicon brake grease and new boots. Seal the drilled hole with silicon. I have done this with a few honda/acuras.
