Your thinking is not wrong. How much pressure is a diver subjected to,
considering that it is being exerted from all angles? Having two hydraulic
cylinders pressing on opposite sides of the brake disk is a way of
eliminating deflection without making the disk super heavy. Also, the way
the caliper is constructed, the opposing forces balance each other, so you
don't need a super heavy bracket.
