I was removing the calipers last night to swap in some new rotors and KINK the top of the bolt busted off. NOOOOO!!!!
Can someone ID this bolt for me so I can get new ones. I want more on hand before I remove any of the others. I'm pretty sure its a M10 - 1.25 x ? Anyone know the length? I should really invest in a service manual. Thanks. - Jamie

I had the same problem and unfortunately you will have to go to the dealer to get a new bolt, they are sort of unique..

Also I am also assuming the other half of the bolt is broken off in the caliper pin, so you will need a new one of those as well. It was around $8 for both of them.
