GM caliper bolts have been Torque to Yield (TTY) for over twenty years. Most GM Dealers have not yet seen that memo, nor has the enthusiast market. There are a handful of informed GM and independent service shops that do the job right, but they are in the minority.
Reusing the bolts will have no negative effect most of the time. Some of the time the caliper bolts come loose and fall out. A caliper stuck between the inner barrel of your wheel will sheer the control arm attachment points. A failure of this nature can be fatal and at the very least expensive.
The ONLY correct way to install a GM brake caliper is with NEW TTY bolts. If for some reason you cannot use a brand new TTY bolt use high temperature LocTite and the German technical spec gudentight.
