Tom, you had a problem with the brake pucks not retracting, as I recall. The same happened to me. The solution was to take the caliper apart and to remove the puck seals. Then, all corrosion in the seal grooves was scraped out using a dental pick. Next, the groove surfaces were polished using a Dremel tool. Then, the caliper was put back together.
Corrosion behind the seals was pushing them up against the puck and they would not allow the puck to retract. Removing the corrosion did the trick.
