Suzuki AN650 2002 Service Manual page 41

The brake system of this motorcycle is filled with a
glycol-based brake fluid. Do not use or mix different
types of fluid such as silicone-based or petro-
leum-based. Do not use any brake fluid taken from
old, used or unsealed containers. Never re-use brake
fluid left over from the last servicing or stored for a
long period.
Brake fluid, if it leaks, will interfere with safe running
and immediately discolor painted surfaces. Check the
brake hoses and hose joints for cracks and fluid leak-
age before riding.
BRAKE PADS
The extent of brake pad wear can be checked by observing the
grooved limit A on the pad. When the wear exceeds the
grooved limit, replace the pads with new ones. (
Replace the brake pad as a set, otherwise braking per-
formance will be adversely affected.
