BLEEDING THE HYDRAULIC BRAKE
SYSTEM
Bleed the hydraulic brake system whenev-
er:
S the system is disassembled.
S a brake hose is loosened, disconnected or
replaced.
S the brake fluid level is very low.
S brake operation is faulty.
S Be careful not to spill any brake fluid or allow
the 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.
1. Bleed:

f. Fully pull the brake lever or fully press down

Loosening the bleed screw will release the pres-
sure and cause the brake lever to contact the
throttle grip or the brake pedal to fully extend.
