OK. I did everything you did. Soaked, scrubbed, soaked, scrubbed. Still dragged. Finally spoke with a retired 77 YO mechanic who helped me. The metal groove that the o ring sits in on the piston side of the caliber required scraping with a nail or toothpick. I did not believe the old guy but I tried it (since I was out of ideas). I had soaked it and scrubbed it but the inside of the groove had just enough corrision to keep the piston from completely retracting. Worked great for 2 or 3 years and just had to do it again this year. Good for several more years I hope. Ride Safe.
