It's important to first wipe off any mud or rust from the brake hub, where the rotor will attach before replacing it. After that, fit the brake rotor onto the studs and bearing on the hub. Move the caliper over the brake rotor and make sure it's aligned with the knuckle. Mount the bolts for your calipers and apply 190 Nm (140 ft. lbs.) tightening pressure. Then, fit the tire and wheel onto the car, tightening the wheel nuts to 150 Nm (or 110 ft. lbs.). After lowering the vehicle, press the brake pedal forcefully several times before you drive away. After doing the previous activities, check and adjust the brake fluid level when needed. Watch out, because initial braking is often less powerful if you've fitted new brake rotors or pads. Following the replacement, take the vehicle for a spin, stopping 1-2 times to remove and polish the brake residue.
