Front Caliper mounting bolt

what size socket do i need to remove those two bolts that hold on the front caliper? i realize they are not normal, so i need to go and buy the correct socket and id like to make the trip only once lol

any help would be great! thanks

Should be a 3/8 inch allen "bit" or wrench, best to get one that goes on a standard ratchet drive.

perfect! thank you
