MAINTENANCE
Brakes
The front and rear brakes are hydraulic disc brakes, activated by moving
the single brake lever toward the handlebar. The auxiliary foot brake is
also hydraulic. Both brake systems are self-adjusting.
Brake Inspections
The following checks are recommended to keep the brake system in
good operating condition. Check more often if brakes are used heavily
under normal operation.
1. Always keep brake fluid at an
adequate level. See page 31.
2. Check the brake system for fluid
leaks.
3. Check the brakes for excessive
travel or spongy feel.
4. Check the friction pads for wear,
damage and looseness. Replace
the pads when the friction mate-
rial is worn to 1 mm.
5. Check the security and surface
condition of the disc.
