BLEEDING THE HYDRAULIC BRAKE
SYSTEM
ss
WARNING
Bleed the hydraulic brake system whene-
ver:
• 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 or
brake fluid reservoir to overflow.
• When bleeding the hydraulic brake system,
make sure there is always enough brake
fluid before applying the brake. Ignoring this
precaution could allow air to enter the
hydraulic brake system, considerably lengt-
hening 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.
