Then when everything gets hot and starts to expand, the bolt is stretched beyond its limit and either loosens up or fails outright. Either of which is a recipe for disaster!

Thank you so much for that little nugget of info! My powdercoating business focuses on brake calipers. I've done 2 sets of rotor hats for AP racing setups on the 350Z. Fortunately, they were both show cars and the brakes will probably never even get warm, but I now will not do them at all, or just mask the rest of the rotor if I do and leave them assembled.

When the ring wears out do they have to buy a whole new assembly? Or send them in to have them re-ringed?
