Just need to know the bolt size of the bolt that holds the caliper into the plate behind the rotor. Also would an autozone have anything like this or maybe i can get one at a homedepot?

Its the rear tire bolt that goes into the hole right behind the rotor. I lost it going down the road and need to know the size so i can replace it .

No comment on who's fault it is.

If anyone has this info please post!!

Thanks,
Brian
