Are those two bolts on the caliper on the other side of the car also shallow headed?
Yes.
I’m almost tempted to replace them, but I understand they are some sort of “Super Grade 8” bolt.
OTOH, as long as either I or my 400-mile-away mechanic buddy always do the brake jobs, no way during my ownership will the bolts ever be torqued in at 180 lb-ft!
(I’m going to pick up a torque wrench too.)
