I went to change my brake pads on the front yesterday.
Me, being a moron, did't realize you have to place a wrench on the sleeve on the back of the caliper to remove the retaining bolts. So, like an idiot I tried and tried for minutes to get the bolt to come out before it occured to me I was doing it wrong. It was simply spinning the bolt & Sleeve.

The question is did possibly do any damage by spinning the bolt, and sleeve around like that?

 

Are you still worried about that?

 

I think you may have caused seriously irreversible damage...scratches!! I seriously doubt you caused any damage, but on a positive note you did learn something about brakes!

 

Yea, I agree there's no way you could have caused any damage.

 

You didn't hurt anything. If you were to take the caliper and bracket off of the car you would see how those "bolts" are really a pin with a bolt in the end. All you did was turn the pin around in the hole. The pin just slides into the bracket.
