A soft or spongy feeling in the brake lever
can indicate the presence of air in the brake
system. Before the vehicle is operated, the
air must be removed by bleeding the brake
system. Air in the brake system will consid-
erably reduce braking performance.

BLEEDING THE HYDRAULIC BRAKE SYS-
TEM
WARNING
EWA13100
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.
TIP
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.
1. Bleed:
