  Q: How do you properly replace and install brake discs on Nissan Murano?

  A: Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and install the lug nuts to hold the disc in place; if the lug nuts don't contact the disc when screwed on all the way, install washers under them. Remove the Brake Caliper without disconnecting the brake hose, and suspend it out of the way with a piece of wire. Visually inspect the disc surface for score marks and other damage; light scratches and shallow grooves are normal, but deep scoring requires disc removal and refinishing by an automotive machine shop. Check both sides of the disc, as severe wear from neglected brake pads may necessitate replacement. To check disc runout, place a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc; the reading should not exceed the specified allowable runout limit. If it does, the disc should be refinished. Resurfacing the discs when replacing brake pads is advisable for a smooth finish and a perfectly flat surface, which helps eliminate brake pedal pulsation. If not resurfacing, at least remove the glaze from the surface with emery cloth using a swirling motion. The minimum wear thickness is cast into the disc, which can be checked with a micrometer. Remove the two caliper mounting bracket bolts and detach the caliper mounting bracket, ensuring the parking brake is fully released for rear discs. Remove the lug nuts holding the disc in place and take the disc off the hub; if a rear disc won't come off, remove the rubber plug from the parking brake adjuster hole and use a small screwdriver to turn the star wheel to retract the Parking Brake Shoes. Place the disc in position over the threaded studs, install the caliper mounting bracket over the disc and tighten the bolts, then install the caliper and tighten its bolts. Finally, install the wheel, lower the vehicle to the ground, tighten the lug nuts, and depress the brake pedal a few times to bring the brake pads into contact with the disc, checking the operation of the brakes carefully before driving.
