The two 10mm allen bolts have a locking agent on them and I imagine are designed to be permament (Real OEM shows the caliper and backing plate as a unit).

I looked all this up because I am going to change out my OEM struts for some Koni FSD struts and you drop the swivel bearing and strut as a unit to access the strut for replacement.

Uh oh.?.? Next time I'm at my dealer I will let them know how I removed the bolts and maybe have them reinsert new bolts with a locking agent just to safe. Thanks.

EDIT: My service techs have advised that they remove the calipers using the allen bolts and don't remove the entire caliper bracket.
