Does anybody know if this bolt will work for the rear brembo calipers?

From what I have searched, the required bolt size is M12-1.75 x 35mm grade 10.9
These bolts don’t seem to be rated at 10.9. It only lists a tourque rating of 98 lb.ft. (Manual specs 58-73 lb. ft.) And a tensile strength of 180,000 psi. In the description they state it is superior to grade 8.
I can pick them up cheaper then the factory one from the dealer.

 

It'll work, but the black oxide finish will rust, especially when you throw some heat at it. Won't be a problem for a long while as far as strength is concerned, but the rust could cause them to seize up and damage the caliper threads. OE bolts are zinc coated.

 

You can buy the OEM bolts, I think this is the one you're looking for.

That part number might even be in stock at your local Nissan / Infiniti dealership.
