  Q: How do you properly remove and install a brake disc while ensuring optimal brake performance on Nissan Quest?

  A: Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and install the lug nuts with 3 mm thick washers under them to hold the disc in place. Remove the Brake Caliper without disconnecting the brake hose, and suspend the caliper out of the way with a piece of wire while supporting it from the strut/coil spring assembly. Visually inspect the disc surface for scoring or damage; light scratches and shallow grooves are normal, but deep scoring over 0.015 inch requires refinishing by an automotive machine shop. Check both sides of the disc. If pulsation during braking is noted, suspect disc runout by placing a dial indicator about 1/2-inch from the outer edge of the disc, ensuring the lug nuts are tight, then rotating the disc to check the runout. The reading should not exceed the specified allowable runout limit; if it does, have the disc refinished. It is recommended to resurface the discs regardless of the dial indicator reading to ensure a smooth finish and flat surface, eliminating brake pedal pulsation. If not resurfacing, remove glazing from the surface with emery cloth or sandpaper using a swirling motion. Ensure the disc is not machined to a thickness less than the minimum allowable thickness, which is stamped on the disc, and check the thickness at several points with a micrometer. Remove the two caliper-to-steering knuckle bolts and the brake caliper. Remove the lug nuts that held the disc in place and take the disc off the hub. If the disc is stuck, thread two bolts into the holes provided and tighten them alternately until the disc is free. Place the disc in position over the threaded studs, then install the caliper and brake pads over the disc, tightening the caliper mounting bolts to the specified torque. Install the wheel, lower the vehicle to the ground, and depress the brake pedal a few times to bring the brake pads into contact with the disc. Bleeding of the system is only necessary if the fluid hose was disconnected from the caliper. Check the operation of the brakes carefully before placing the vehicle into normal service.
