Park vehicle on a level surface. Engage the parking brakes on the Nissan.
Loosen the lug nuts before you jack up your Nissan but don't remove them yet.
Jack up the car and remove the wheel.
Next, you will need to loosen the 14mm caliper bolts to get the brake caliper out.
Remove brake caliper. Do not let the brake caliper hang on the brake hose.
Press the brake caliper piston in. Pistons need to be pushed back into the caliper in order to accommodate the new rotor and brake pad. Because the rear brake caliper has the emergency/parking brakes integrated into it, the cylinder may need to be rotated for it to go back.
Use a breaker bar to remove bracket bolts.
Remove the rotor from the car.
Install the new rotor. Reinstall the caliper bracket and torque it to 85Nm.
Clean shims and apply grease to the back of brake pads. Apply silicone-based grease to the ends of the brake pads.
Rember to clean and apply grease to caliper guide pins.
Reinstall new brake pads. Install the brake caliper bolts and torque to 20-25 ft/lb.
Install the wheel. Slowly lower your Quest to the ground. Torque the lug nuts in a star pattern to the manufacturer's recommendation (70-90 ft-lbs.)
