There is only one caliper bolt on top and it pivots at the bottom.
How to remove front brake calipers? on 2003 Mazda Mazda6
There are 2 bolts holding the caliper in place. You will need an 18mm Allen Head wrench, or one that fits into a socket would be better. Just removing the one bolt at the top and trying to pivot might work, but the brake line will hold it back. I found it easier to remove both bolts and remove the one bolt holding the brake line by the shock to give enough 'play' to remove the caliper.
Thanks, you are absolutely correct.
