MAINTENANCE

Brakes

Hand Brake

The front and rear brakes are hydraulic disc brakes, activated by moving the single brake lever toward the handlebar. These brakes are self- adjusting.

Under normal operation, the diaphragm extends into the reservoir as fluid level drops. If the fluid level is low and the diaphragm is not extended, a leak is likely and the diaphragm should be replaced. To ensure proper diaphragm operation, always fill the reservoir as needed whenever the cover is loosened or removed. Do not overfill.

WARNING! An over-full master cylinder may cause brake drag or brake lock- up, which could result in serious injury or death. Maintain brake fluid at the recommended level. Do not overfill.

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 32.

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 brake pads when

they are worn to 3/64" (1 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.

Auxiliary Foot Brake

The hydraulic auxiliary brake system requires no adjustment. Check the brake fluid level frequently for the auxiliary brake system. See page 34.
