BLEEDING THE HYDRAULIC BRAKE SYS-
TEM
WARNING
Bleed the hydraulic brake system whenev-
er:
S The system was disassembled.
S A brake hose was loosened or removed.
S The brake fluid level is very low.
S Brake operation is faulty.
NOTE:
S Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir to over-
flow.
S When bleeding the hydraulic brake system,
make sure that there is always enough brake
fluid before applying the brake. Ignoring this
precaution could allow air to enter the hydrau-
lic brake system, considerably lengthening the
bleeding procedure.
S 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.
