Never had any issues with braking bolts! The dust boots on the stock calipers melt away and the caliper itself turns a yellowish color. The brakes still work fine. I've never had any issues with fade (I use ATE fluid and change frequently). I actually think the stock brakes are very good except for the dust boots.
That said, others have had issues with the ceramic 'caps' crumbling away. I have not personally had that issue, but I suspect temperature could be a cause there as well.
No idea where to mount said misters yet.
