HYDRAULIC BRAKE
15-4
SERVICE INFORMATION
GENERAL
Spilled brake fluid will severely damage instrument lenses and painted surfaces. It is also harmful to some rubber parts. Be
careful whenever you remove the reservoir cap; make sure the front reservoir is horizontal first.
• This section covers service of the conventional brake components of the brake system. For Anti-lock Brake System
(ABS) service, see page 16-4.
• A contaminated brake disc or pad reduces stopping power. Discard contaminated pads and clean a contaminated disc
with a high quality brake degreasing agent.
• Never allow contaminates (e.g., dirt, water) 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 4 brake fluid from a sealed container when servicing the system. Do not mix different types of
fluid as they may not be compatible.
• Always check brake operation before riding the motorcycle.

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 and OSHA-approved vacuum cleaner.
