Lesson 6/Learning Event
Always check the by-pass part in the master cylinder
to be sure it is clear when the system is at rest.
Never probe in the small by-pass hole. When applying
the brakes, there should be a ripple in the fluid in
the master cylinder reservoir. After applying brakes
a few times, there should also be a ripple caused by
returning fluid.
Checking visually with a bright
light is advisable.
WARNING
IF THE BY-PASS PART IS NOT CLEAR, BRAKE SYSTEM LOCK UP
COULD OCCUR AND CAUSE SERIOUS DAMAGE.
Caution
Always check the brake pedal or linkage for free
travel.
Adjust in accordance with the appropriate
technical manual as needed.
FILLER/BLEEDER MAINTENANCE
Bleeder/Filler Tank
The tank and fittings should be kept clean at all times. Never allow the
tank or fittings to come into contact with mineral oil products such as
kerosene, motor oil, and thinners. Do not use water to clean the tank at
anytime.
Fittings
Fittings cleaned in anything other than brake fluid should be thoroughly
dried inside and out before use.
Air Chamber
Periodically clean out the air chamber in order to remove any water, oil,
and dirt sludge that may enter from the air system used to fill the tank.
Remove and rinse the safety valve (part number T4669) with clean alcohol.
Be sure to drain and dry it completely to avoid contaminating the next fluid
fill.
Fluid Chamber
The fluid chamber needs no attention unless dirt or improper fluid has to be
removed.
Rinse it with clean alcohol, and drain and dry the chamber
completely to avoid contaminating the next fluid fill.
