BLEEDING THE HYDRAULIC BRAKE SYS-
TEM
WARNING
Bleed the hydraulic brake system whenever:
S the brake system was disassembled,
S a brake hose was loosened, disconnected,
or replaced,
S the brake fluid level is very low,
S brake operation is faulty.
1. Remove:
S muffler

NOTE:
S Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir or brake
fluid reservoir to overflow.
S When bleeding the hydraulic brake system,
make sure there is always enough brake fluid
before applying the brake. Ignoring this pre-
caution could allow air to enter the hydraulic
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.
3. Bleed:
S hydraulic brake system

el with recommended brake fluid.
