Nissan Murano: Front Disc Brake / Disc Brake Rotor

Inspection and Adjustment

INSPECTION

Appearance

Check surface of disc brake rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.

Runout

Check the wheel bearing axial end play before the inspection. Refer to Inspection.

Secure the disc brake rotor to the wheel hub and bearing assembly with wheel nuts at two wheel nut locations.

Inspect the runout with a dial gauge, measured at 10 mm (0.39 in) inside the disc edge.

Find the installation position with a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation position by one hole at a time if the runout exceeds the limit value.

Refinish the disc brake rotor if the runout is outside the limit even after performing the above operation. When refinishing, use Tool.

CAUTION:

• Check in advance that the thickness of the disc rotor is wear thickness + 0.3 mm (0.012 in) or more.

• If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc brake rotor. Refer to Removal and Installation.

Thickness

Check the thickness of the disc brake rotor using a micrometer. Replace the disc brake rotor if the thickness is below the wear limit.

ADJUSTMENT

CAUTION:

• Burnish contact surfaces between brake pads and disc rotor according to the following procedure after refinishing the disc rotor, replacing brake pads or if a soft pedal occurs at very low mileage.

• Be careful of Nissan Murano vehicle speed. Brakes do not operate firmly/securely until pads and disc rotor are securely seated.

• Only perform this procedure under safe road and traffic conditions. Use extreme caution.

Drive the vehicle on straight, flat road.

Depress the brake pedal until the vehicle stops.

Release the brake pedal for a few minutes to allow the brake components to cool.

Repeat steps 1 to 3 until pad and disc rotor are securely seated.
