Syringe

Oil funnel

Tube holder

Oil stopper

Tube holder installation direction

The level of liquid inside the funnel will drop at this time, so keep filling the funnel
with oil to maintain the level of liquid so that air is not drawn in (air does not get
inside).

< In case of a bleed nipple type caliper >

Set a 7 mm socket wrench in place, fill the syringe with oil,
and then connect a tube to the bleed nipple. Secure the bleed
nipple and the tube with a tube holder, and then loosen the
bleed nipple by 1/8 of a turn to open it. Push the plunger of
the syringe to add oil. The oil will start coming out from the
oil funnel. Continue adding oil until there are no more
air bubbles mixed in with the oil that is coming out.

Remove the bleeding tool as shown in the illustration, fill
the reservoir tank with oil and then replace the reservoir
tank cover. Fill the reservoir tank to overflowing with oil
while replacing the cover to ensure that no air bubbles
remain inside the reservoir tank. In addition, be careful not
to get any oil on parts such as the rotor and brake pads.

Oil stopper

O-ring

If the brake lever is then operated, air bubbles in the system will rise up through the port into
the oil funnel. Once the bubbles stop appearing, depress the brake lever as far as it will go.
The normal condition is for the lever to be stiff at this point.

With the spacer for bleeding (yellow) still attached to the calipers, place the bicycle into a bicycle
stand or similar as shown in the illustration.

Be sure to read the Service instructions for “Adding mineral oil and bleeding air” together with
these service instructions.

Install the tube holder as shown in the illustration.
Make sure that the direction of installation is correct.

1.

Cover the reservoir tank with the
bleeding tool which has the oil funnel
attached, and then secure with the
clamp as shown in the illustration.

Note :

Be careful not to overtighten the oil
funnel when attaching it.

Turn the lever unit so that the top of the reservoir tank is parallel to the

Note : When reassembling, set the

diaphragm so that it is aligned at
the same angle as the base of the
reservoir tank.

< ST type >

Reservoir tank

Once there are no more air bubbles mixed in with the oil, temporarily close the bleed nipple
and remove the syringe.

Do not continually squeeze and release the lever at this point.

If this is not observed, air bubbles may remain mixed in with the oil
inside the caliper, and it will take longer to bleed the air. (If the lever is
continually squeezed and released, drain out all of the oil and then add
oil again.)

4.

Set a 7 mm socket wrench in place, and then attach the tube with
the bottle to the bleed nipple as shown in the illustration.
Secure the bleed nipple and the tube with a tube holder, and then
loosen the bleed nipple. After a little while, the oil and air will flow
naturally from the bleed nipple into the tube. In this way it will be
possible to easily extract the greater part of the air remaining
inside the brake system. It may help to shake the hose gently or to
tap the reservoir tank or caliper
gently with a screwdriver or
move the position of the caliper
at this time.

5.

With the brake lever depressed, open and close the bleed nipple in rapid
succession (for approximately 0.5 seconds each time) to release any air
bubbles which may be in the calipers. Repeat this procedure about 2 to 3
times. Then tighten the bleed nipple again.

Tightening torque:

4 - 6 N·m {35 - 52 in. lbs.}

8.

Plug the oil funnel with the oil stopper so that the side with
the O-ring attached is facing downward.

Wipe away any oil which has flowed out.

Once air bubbles stop coming out from the bleed nipple, temporarily
tighten the bleed nipple.

< In case of a bleed boss type caliper >

Fill the syringe with sufficient oil.
After attaching the arm bush to the end of the
tube, connect the tube to the bleed boss.
Fasten the tube with the tube holder so that it
will not be disconnected.
Loosen the bleed screw by 1/8 of a turn to
open it.
Push the plunger of the syringe to add oil. The
oil then starts coming out from the oil funnel.
Continue adding oil until there are no more air
bubbles mixed in with the oil that is coming out.
