BLEEDING THE BRAKE SYSTEM (XP500A)
WARNING
Bleed the ABS whenever:
• the system is disassembled.
• a brake hose is loosened,
disconnected or replaced.
• the brake fluid level is very low.
• brake operation is faulty.
NOTE:
• Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir to over-
flow.
• When bleeding the ABS, make sure 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.
