But we aren't stretching the bolts beyond the tensile or up to the yeild strength? By the same arguement, I would need to replace my lug nuts and studs everytime I take a tire off.

Is the requred torque (I thing its 63 ft-lbs for the M12 x 1.5) exceeding the tensile strength of the bolt? If it is, I would step up to a Grade 8 bolt or higher. And should we be worried about bracket failure? If the bolt is stretching, then the bracket is also deforming and the threads in the bracket under tension. And the caliper itself is under a compression load. All potential failure conditions.
