Nissan 40206-EG000 Rotor-Disc Brake,Front

Loosen the wheel lug nuts, raise the vehicle and support it securely on jackstands, then remove the wheel. Remove the brake caliper, suspending it out of the way with a piece of wire. Reinstall two lug nuts with washers to hold the disc securely against the hub, then visually check the disc surface for score marks, cracks and other damage. To check disc runout, place a dial indicator at a point about 1/2-inch from the outer edge of the disc and set the indicator to zero. An indicator reading that exceeds 0.003 inch could cause pulsation upon brake application and will require disc refinishing by an automotive machine shop or disc replacement. If disc refinishing or replacement is not necessary, deglaze the brake pad surface on the disc with emery cloth or sandpaper. The disc must not be machined to a thickness less than the specified minimum refinish thickness, which is cast into either the front or backside of the disc. Remove the caliper mounting bracket, mark the disc in relation to the hub, then remove the disc. Clean the hub flange and the inside of the brake disc thoroughly, then install the disc onto the hub assembly. Install the caliper mounting bracket and brake pads, then install the wheel and lower the vehicle to the ground. Tighten the wheel lug nuts, depress the brake pedal a few times to bring the brake pads into contact with the disc, then check the operation of the brakes carefully before placing the vehicle into normal service.

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.
