BLEEDING THE HYDRAULIC BRAKE SYSTEM

BLEEDING THE HYDRAULIC BRAKE
SYSTEM
w
Bleed the hydraulic brake system whenever:
99
the system is disassembled.
99
a brake hose is loosened, disconnected or
replaced.
99
the brake fluid level is very low.
99
brake operation is faulty.
NOTE:
9
Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir to overflow.
9
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.
9
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.
