You can use a cheater bar on the brake caliper mounting bolts.
Get a long hand 1/2 inch swivel head breaker bar..
that will give just the right angle to put a cheater bar over  the end
of it  , outboard of the fender/body area.
Turn the steering to full lock to facilitate the angle on each side of
course.

180to 200 ft lbs sounds like plenty enough to me.
I like to put the tiniest bit of copper anti-seize on the threads and
shanks of the bolts. Less than  'barely any'  almost  ..but something
other than bare metal-to-metal.
