If the lever isn't stiff, adjust by the following
procedure.
When the lever is depressed once
more, bubbles will rise up and be
released into the reservoir tank.
It can be useful to shake the hose
gently or shift the position of the
calipers 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.
6.
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.
7. Return the brake lever to its original position.
Note:
Do not use brake fluid fillers, as they can cause
small bubbles of air to form, and such bubbles
can cause severe drops in braking performance.

Remove the pad spacer, and then set the wheel which
has the rotor onto the frame.
If using post-type caliper mounting bosses, use a
Shimano adapter (F: Y8B298040; R: Y8B298070). Be
sure to use the 170 mm rotor when using the front
adapter.
Start with two 0.5 mm thick shims, and use the 0.2
mm shims for fine tuning. tighten the calipers, and
check that the calipers and the rotor do not interfere
with each other. Next, the caliper fixing bolts do not
contact the rotor. If there is any interference, or if it
looks as though interference might occur, insert a 2
mm spacer in the position shown in the illustration.
