Hi everyone. Doing my first rotor and brake change. The fronts went off without a hitch. However, I pretty well chewed up the head of the bottom 19MM mounting bolt for the caliper bracket.

I went to autozone for a replacement, and this is what they had. I am unsure if it is the proper bolt grade. It is M12-1.25X35 Class 8.8 B-75. This is what the package says.

Any help greatly appreciated. Thank you.

New bolt is left, OEM bolt is right.

 

Just clean up the head of the existing bolt with as file and stop using crappy 12 point sockets A 6 point socket will grab that just fine. Torque everything to spec, I think that bolt is 32 ft/lbs.
