ADJUSTMENT AFTER INSTALLATION

Brake Burnishing Procedure

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

CAUTION:

• Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are

securely fitted.

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

Drive vehicle on straight, flat road.

Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.

Drive without depressing brake for a few minutes to cool the brake.

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