WOW OW WOW, You did indeed catch a "break" of sorts having it lock up at a snails pace! The only possible internal damage would be to the "o" ring on the piston itself. The caliper is so small it cannot retain heat for an extended period so I very much doubt the "o" ring got hurt. You can find out by blowing compressed air into the bleeder. That will force the piston out of the caliper so it can be inspected. BE CAREFULL use a regulator as the piston can come out with a lot of force. (kinda like a potato gun) 2-3 psi will do it. I also seriously doubt the small amount of drag had anything to do with fuel economy. If the drag was that high you would have smelled something burning each time you parked, or felt the lurching each time you were slowing down. Blue Lok-tite is the ticket here. In fact New mounting bolts has it pre applied. The key is the heat generated each time you apply the brake. Without a thread lok compound these bolts will always expand/ contract until they work loose. If Santa has anything helpfull, I will put it aside for you. I've been RED SUIT training the dogs for 2 weeks now. Sorry to here repair troubles today, but a good movie, a few laughs, hopefully a very MERRY X-MAS, and last but not least MASS IRIDIUM to you , and yours!
