HYDRAULIC BRAKE

SERVICE INFORMATION

GENERAL

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.

• Avoid breathing dust particles.

• Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.

Spilling brake fluid will severely damage instrument lenses and painted surface. It is also harmful to some rubber parts. Be careful whenever you remove the reservoir cap; make sure the front reservoir is horizontal first.

• A contaminated brake disc or pad reduces stopping power. Discard contaminated pads and clean a contaminated disc with a high quality brake degreasing agent.

• Check the brake system by applying the brake lever or pedal after the air bleeding.

• Never allow contaminates (dirt, water, etc.) to get into an open reservoir.

• Once the hydraulic system has been opened, or if the brake feels spongy, the system must be bled.

• Always use fresh DOT 3 or DOT 4 brake fluid from a sealed container when servicing the system. Do not mix different types of fluid, they may not be compatible.

• Always check brake operation before riding the motorcycle.
