HYDRAULIC
Frequent inhalation of brake pad and shoe dust, regardless of material composition, could be hazardous to your heal
• Avoid breathing dust particles.
• Never use
an
air hose or brush to clean brake assemblies. Use
an
OSHA-approved vacuum cleaner.
NOTICE
I
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 master cylinder 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 after the air bleeding.
Never allow contaminants (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 scooter.
