SERVICE INFORMATION
GENERAL
ACAUTION
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-approve)d vacuum cleaner.
A contaminated brake disc or pad reduces stopping power. Discard contaminated pads, and clean a contaminated disc
with a high quality brake degreasing agent.
Spilled brake fluid will severely damage the plastic parts and painted surfaces. It is also harmful to some rubber parts.
Be careful whenever you remove the reservoir cap; make silre the reservoir is horizontal first.
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 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 vehicle.
