BLEEDING THE HYDRAULIC BRAKE
SYSTEM
Bleed the hydraulic brake system when-
ever:
the system was disassembled,
a brake hose was loosened or removed,
the brake fluid level is very low,
brake operation is faulty.
1. Remove:
reservoir cap
diaphragm 1
Be careful not to spill any brake fluid or al-
low the brake master cylinder reservoir or
brake fluid reservoir to overflow.
When bleeding the hydraulic brake sys-
tem, 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.
