No the carrier is the part that the pads are in. It's bolted the the knuckle with 2 17mm bolts, they torque to 80 ft/lbs. The caliper, is in turn bolted to the carrier by 2 12mm (or 10mm, it's been awhile) bolts. They don't need to be torqued too hard, just give a couple grunts. The wheel is held on by 4 19mm nuts, they are torqued to 80 ft/lbs.
