My suggestions, if the calipers are not leaking, you only need to replace pads and sensors. Repack the wheel bearing, and replace rotor if necessary. Add the caliper repair kits only if it leaks.

I have not seem your car, I don't think any of the parts would wear out at 100k. If you think replacing the brake's hardware would make you feel better. Then you also need to replace the rear brakes as well.
