Bleeding; Storage; Cleaning And Care - Craft Meyer 10002558 Mode D'emploi

• Do not under any circumstances mix a DOT 5 brake fluid with
classes DOT 3, DOT 4 or DOT 5.1.

4.2 | Bleeding

Place a suitable box end wrench on the bleed screw on the hydraulic cylinder
which you wish to bleed (if a system has more than one hydraulic cylinder, the
one furthest from the control lever is bled first). Then connect the short ends of
the hose on the bleed screw (1) and place the long end of the hose in an empty
container (e.g. jam jar or similar). The fluid must flow out through the valve in
the direction indicated by the arrow so that the valve can cut off any backflow.
Open the bleed screw with the box end wrench on the hydraulic cylinder by half a
turn. Then align the control lever horizontally, e.g. to the handlebars, and open the
reservoir. Now use the hand or foot lever pump the old fluid out of the system –
you can see how it and any air is forced out of the system through the hose
and the valve and into the container. Before the reservoir empties completely,
pour in fresh hydraulic fluid (do not wait too long – if the reservoir does empty
completely, air will be sucked into the system and will have to be laboriously
pumped out again). Continue pumping until only fresh, clean, bubble-free fluid
is flowing through the hose and into the container. If necessary, top up again
with brake fluid. To complete the bleeding process, hold the hand or foot lever
in the pulled/pushed position with the last stroke of the pump and close the
bleed screw on the hydraulic cylinder at the same time. Then move the operating
lever back and forth a few times – a good, solid pressure point must build up.
This indicates that the system has been bled thoroughly (otherwise, repeat the
bleeding process). Then top up the reservoir to the maximum mark, wipe the
rubber seal in the cover dry and seal the hydraulic unit again. Remove the bleed
valve from the bleed screw and before taking to the road again check once more
that the hydraulic unit on the vehicle is fully functional and roadworthy.

5 | Storage

Handle the brake bleed valve with care. It is best to store it cleaned and in a dry
place, in the original packaging.

6 | Cleaning and care

After every use, the brake bleed valve is flushed thoroughly with clear water and
then dried.
