J. BLEEDING THE HYDRAULIC

BRAKE SYSTEM

WARNING

Bleed the hydraulic brake system whenever:

•••••

the system was disassembled,

•••••

a brake hose was loosened or removed,

•••••

the brake fluid level is very low,

•••••

brake operation is faulty.

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 that there is always enough brake fluid before

applying the brake. Ignoring this precaution 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:

brake lever or brake pedal.

i.

Repeat steps (e) to (h) until all of the air bubbles

have disappeared from the brake fluid in the

plastic hose.
