BLEEDING THE HYDRAULIC BRAKE
SYSTEM
WARNING
Bleed the hydraulic brake system when-
ever:
• the system is disassembled.
• a brake hose is loosened, disconnected or
replaced.
• the brake fluid level is very low.
• brake operation is faulty.
NOTE: NOTE:
• Be careful not to spill any brake fluid or allow
the 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 pre-
caution could allow air to enter the hydraulic
brake system, 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.
