Adding mineral oil and

bleeding air

When carrying out the air bleeding operation for the

BR-M985, you will need the SM-DISC (oil funnel and oil

stopper).

as shown in the illustration. If the

steps are outside this range,

complete air bleeding may not be

possible.

Hose

Calipers

Bleed nipple

I When using the bleed nipple

Set the brake lever so that it is in the riding position at a 45 degree angle to

the ground, and then remove the upper bleed screw and the O-ring and insert

the oil funnel. Do not insert the oil stopper at this time.

Bleed screw

Oil funnel

O-ring

Set a 7 mm socket wrench in place,

fill the syringe with oil, connect a

tube to the bleed nipple, 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.

Bleed nipple

Once there are no more air bubbles mixed in with the oil, temporarily close

the bleed nipple.

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.)

Set a 7 mm socket wrench in place as shown in the

illustration, and then attach the bag to the tube.

Connect the tube to the bleed nipple 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.

Air

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).

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

tighten the bleed nipple.

Bleed nipple

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 - 53 in. lbs.}

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.

Set the lever unit to the horizontal position as shown in the

illustration and tilt it in the direction of 1 by 30 degrees, and

then carry out step 8 to check that there is no air remaining.

Next, tilt the lever unit 30 degrees in the direction of 2, and

carry out step 8 again to check that there is no air remaining.

If any air bubbles appear, repeat the above procedure until

they stop appearing.

10.

Plug the oil funnel with the oil stopper so that the side

with the O-ring attached is facing downward.

11.

Remove the oil funnel while it is still being plugged with

the oil stopper, and then attach the O-ring to the bleed

screw and tighten it until oil flows out to make sure that

there are no air bubbles remaining inside the reservoir

tank.

* Do not operate the brake lever at this time, otherwise

air may get inside the cylinder.

Tightening torque:

0.3 - 0.5 N·m {2.7 - 4.4 in. lbs.}

12.

Wipe away any oil which has flowed out.

Bag

Remove the brake calipers from the frame.

Hold the calipers so that the bleed nipple is facing upward and

then remove the bleed nipple and install the bleed screw. At this

time, tighten the bleed screw until oil flows out to make sure that

there are no air bubbles remaining inside the calipers. After this,

wipe away any oil which has flowed out.

Tightening torque:

4 - 6 N·m {35 - 53 in. lbs.}

I When using the bleed screw

Set the brake lever so that it is in the riding position at a 45 degree angle to

the ground, and then remove the upper bleed screw and the O-ring and insert

the oil funnel. Do not insert the oil stopper at this time.

Remove the bleed screw of the bleed unit from the calipers, and install the

bleeding adapter. Fill the syringe with oil and connect a tube to the bleeding

adapter, and then loosen the bleeding adapter 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.
