Brakes
The front and rear hand brakes are hydraulic disc brakes, activated by
moving the single brake lever toward the handlebar. The auxiliary foot
brakes are also hydraulic disc brakes. All brakes are self-adjusting.
Brake Inspections
Inspect brake components at the intervals outlined in the Periodic
Maintenance Chart beginning on page 91. Check more often if brakes
are used heavily under normal operation.
1. Always keep brake fluid at an adequate
level. See page 106.
2. Inspect hydraulic hoses for leaks, wear
or damage. Replace worn or damaged
hoses promptly.
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 material is worn
to 0.762 mm.
5. Check the security and surface condition of the disc. Clean any
grease using a recommended brake cleaner or alcohol. Do not use
spray lubricants or other petroleum-based products. If you discover
any damage (cracks, excessive corrosion, warping) see your dealer
for service before operating.
