TIP
• Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir or brake
fluid reservoir to overflow.
• When bleeding the ABS, make sure that there
is always enough brake fluid before applying
the brake. Ignoring this precaution could allow
air to enter the ABS, considerably lengthening
the bleeding procedure.
• If bleeding is difficult, it may be necessary to let
the brake fluid settle for a few hours.
• Repeat the bleeding procedure when the tiny
bubbles in the hose have disappeared.
1. Remove:
• Right side cover
Refer to "GENERAL CHASSIS" on page 4-1.
2. Bleed:
• ABS
