Anti-seize on brake caliper bracket?

Rod bolts, head bolts, main bearing cap bolts are all put together using assembly lube so that you get the proper stretch when you torque them. Some anti-seize will not be a problem. Of greater concern is the number of times those bolts have been removed and re-torqued. Every time you torque that bolt you stretch it a bit further. Eventually, the bolt will fail, not by loosening, but by breaking because it was overstretched. On our race car, we replace any bolt that would be torqued more than twice. On my personal vehicle, I follow that same rule for any safety related items like brakes and suspension / steering. Anything else, like wheel studs, I will usually go 4 or five torquings before replacing.
