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.

Becomes

stiff

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.

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.

Installation of the calipers and

securing the hose.

< BR-M755 >

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.
