Spilled brake fluid will severely damage instnlment less, wind screen alld painted surfaces. Be very careful whenever
your remove the reservoir cap: Make sure the front resen'oir is horizontal first.
Never allow contaminants (din. waler. ere.) to get into the hydraulic brake system.
• The GOLD WING is equipped with a unified brake system which provides simultaneous braking action of the right front
and rear disc brakes through application of the foot operated brake pedal. The hand operated brake lever activates the left
front disc brake which is independent of the unified system (Except G type).
• The front brake can be removed without disconnecting the hydraulic system. Once the hydraulic systems have been opened,
or if the brakes feel spongy, the system must be bled.
• Do not allow foreign material to enter the system when filting the reservoir.
• Always the fresh DOT 4 brake fluid from a sealed container when servicing the system.
• Always check brake operation before riding the motorcycle.
• Replace the sealing washers whenever the brake hose bolt is removed.
