A slight nitpick, the torque applied to the caliper from the disc, through the pads, does travel through the caliper mounting bolts. It's a lateral force rather then a axial one but it does go through fasteners.

For most designs the calipers sit inside a frame that takes the braking force, and the fasteners simply hold the caliper in alignment within that frame. This wikipedia photo happens to be from an AMC pacer, but it does show the frame that takes the braking torque load (https://en.wikipedia.org/wiki/File:Detail_of_-_AMC_Pacer_-_right_front_disc_brake_and_suspension_system.jpg https://en.wikipedia.org/wiki/File:Detail_of_-_AMC_Pacer_-_r...). The frame is the lighter metal object at the top above the top edge of one of the pads.
