The first thing to do with the front brake rotor is to instal them without removing and replacing and inspect the disc
Brake Pads beforehand. Clean the hub face in order to get any dirt or rust off where the rotor mounts. Then install the brake rotor to the studs that press against the hub and bearing. Position the brake rotor and knuckle then position the disc
Brake Caliper and adapter bracket assembly over the brake rotor. Mount two caliper adapter bracket mounting bolts, inboard and outboard, over the top of the knuckle and tighten to 169 Nm (125 ft. lbs.). Then installation of the tire and wheel assembly can be done and it is tightened down to 135 Nm (100 ft. lbs.) for the wheel mounting nuts. Pump the brake pedal several times to set the pads to the brake rotor while lower the vehicle. Next, readjust the brake fluid level in the reservoir if required and do a road test, bringing the car to a halt numerous times to make sure the brake pads contact the rotor.
