General Safety Information
WARNING
• Please use extra caution to keep your fingers away from the rotating
disc brake rotor during installing or servicing the wheel. The rotor is
sharp enough to inflict severe injury to your fingers if caught within
the openings of moving rotor.
• The calipers and rotor will become hot when the brakes are operated, so do not touch
them while riding or immediately after dismounting from the bicycle, otherwise you may
get burned. Check that the brake components have cooled down sufficiently before
attempting to adjust the brakes.
• The required braking distance will be longer during wet weather. Reduce your speed
and apply the brakes early and gently.
• If the road surface is wet, the tires will skid more easily. If the tires skid, you may fall off
the bicycle. To avoid this, reduce your speed and apply the brakes early and gently.
• Always make sure that the front and rear brakes are working correctly before you ride
the bicycle.
• Be careful not to allow any oil or grease to get onto the rotor and brake pads, otherwise
the brakes may not work correctly.
• If any oil or grease do get on the pads, you should replace the pads.
If any oil or grease gets on the rotor, you should clean the rotor. If
this is not done, the brakes may not work correctly.
• Before riding the bicycle, check that the pad thicknesses are 0.5 mm
or more.
• Vapor lock may occur if the brakes are applied continuously.
To relieve this condition, momentarily release the lever.
Vapor lock is a phenomenon in which the oil inside the brake system becomes
heated, which causes any water or air bubbles inside the brake system to expand.
This can then result in a sudden increase in the brake lever stroke.
• Use only genuine Shimano mineral oil. If other types of oil are used, it may cause
problems with brake operation, and cause the system to be unuseable.
• Be sure to use only oil from a freshly-opened container, and do not re-use oil which has
been drained from the bleed nipple. Old oil or already-used oil may contain water which
could cause vapor lock in the brake system.
• Be careful not to let water or air bubbles to get into the brake system, otherwise vapor
lock may occur. Be particularly careful when removing the cover of the reservoir tank.
• When turning the bicycle upside down or on its side the brake system may have some
air bubbles inside the reservoir tank which are still there when the reservoir tank cover
is replaced, or which accumulate in various parts of the brake system when it is used
for long periods. The S500 disc brake system is not designed to be turned upside down.
If the bicycle is turned upside down or on its side, the air bubbles inside the reservoir
tank may move in the direction of the calipers. If the bicycle is ridden in this condition,
there is the danger that the brakes may not operate and a serious accident could occur.
If the bicycle has been turned upside down or on its side, be sure to operate the brake
lever a few times to check that the brakes operate normally before riding the bicycle. If
the brakes do not operate normally, adjust them by the following procedure.
< If brake operation is sluggish when the lever is depressed >
Set the brake lever so that it is parallel to the ground, and then gently depress the
brake lever several times and wait for the bubbles to return to the reservoir tank. It
is recommended that you then remove the reservoir tank cover and fill the reservoir
tank with mineral oil until no bubbles remain.
If the brakes still operate sluggishly, bleed the air from the brake system.
(Refer to "Adding the mineral oil and bleeding air".)
• If fluid leaks occur, immediately stop using the brakes and carry out the appropriate
repairs. If you continue riding the bicycle while fluid is leaking, there is the danger that
the brakes may suddenly stop working.
• Check that the quick release lever is on the right side (the opposite side to the rotor). If
the quick release lever is on the same side as the rotor, there is the danger that it may
interfere with the rotor, so check that it does not interfere.
• It is important to completely understand the operation of your bicycle's brake system.
Improper use of your bicycle's brake system may result in a loss of control or an
accident, which could lead to severe injury. Because each bicycle may handle
differently, be sure to learn the proper braking technique (including brake lever pressure
and bicycle control characteristics) and operation of your bicycle. This can be done by
consulting your professional bicycle dealer and the bicycle's owners manual, and by
practicing your riding and braking technique.
• The S500 disc brakes are designed for optimum performance when used in
combination with the BR-S500 (calipers), BL-S500 (brake lever), SM-RT62 (rotor) and
Shimano pad unit.
• Obtain and read the service instructions carefully prior to installing the parts. Loose,
worn, or damaged parts may cause injury to the rider.
We strongly recommend only using genuine Shimano replacement parts.
• Read these Technical Service Instructions carefully, and keep them in a safe place for
later reference.
CAUTION
Handling the mineral oil
• Use safety glasses when handling, and avoid contact with eyes. Contact with eyes may
result in irritation.
In the event of eye contact, flush with fresh water and seek medical assistance
immediately.
• Use gloves when handling. Contact with skin may cause a rash and discomfort.
In the event of skin contact, wash well with soap and water.
• Inhalation of oil mist or vapors may cause nausea. Cover nose and mouth with a
respirator type mask and use in a well ventilated area.
If mist or vapor is inhaled, go immediately to an area with fresh air. Cover up with a
blanket. Stay warm and stable and seek professional medical advice.
• Do not drink. May cause vomiting or diarrhea.
• Keep out of reach of children.
• Do not cut, heat, weld or pressurize the oil container, as this may cause explosion or
fire.
• Disposal of Used Oil : Follow local county and/or state codes for disposal. Use care
when preparing oil for disposal.
• Directions : Keep the container sealed to prevent foreign objects and moisture from
getting inside, and store it in a cool, dark area away from direct sunlight or
heat.
Burn-in period
• Disc brakes have a burn-in period, and the braking force will gradually increase as the
burn-in period progresses. Make sure that you are aware of any such increases in
braking force when using the brakes during the burn-in period. The same thing will
happen when the brake pads or rotor are replaced.

I Installation of the hose
Refer to the Service Instructions for the SM-BH59 brake hose (SI-8H20) for
details on installing the hose.
Do not let the hose become twisted when installing. Make sure that the calipers
and levers are in the positions shown in the illustrations.
When cleaning with a compressor
• If disassembling the caliper body to clean the internal parts using a
compressor, note that moisture from the compressed air may remain on the
caliper components. Let the caliper components dry sufficiently before
reassembling the calipers.
Note
• If the brake caliper mounting boss and the dropout are not parallel, the rotor
and caliper may touch.
• When the bicycle wheel has been removed, it is recommended that pad
spacers should be installed. The pad spacers will prevent the piston from
coming out if the brake lever is depressed while the wheel is removed.
• If the brake lever is depressed without the pad spacers installed, the pistons
will protrude further than is normal. Use a flat-tipped screwdriver or similar tool
to push back the brake pads, while being careful not to damage the surfaces of
the brake pads. (If the brake pads are not installed, push the pistons straight
back in, while being careful not to damage them.)
If it is difficult to push the brake pads or pistons back, remove the reservoir
tank cover and then try again. (Note that some oil may overflow from the
reservoir tank at this time.)
• Use isopropyl alcohol, soapy water or a dry cloth when carrying out cleaning
and maintenance of the brake system. Do not use commercially-available
brake cleansers or silencing agents, as they can cause damage to parts such
as seals.
• Do not remove the pistons when disassembling the calipers.
• If the rotor is worn, cracked or warped, it should be replaced.
Adding mineral oil and bleeding air
• Parts are not guaranteed against natural wear or deterioration resulting from
normal use.

Maintenance
Note:
The S500 brake system is designed so that as the brake pads become worn,
the pistons gradually move outward to automatically adjust the clearance between
the rotor and the brake pads. Therefore, you need to push the pistons back to
their original positions when replacing the brake pads.
Brake pads
Remove the wheel from the frame, and remove the
brake pads as shown in the illustration.
Split pin
Clean the pistons and surrounding area.
Set the brake lever so that it is parallel to the ground,
and then remove the reservoir tank cover.
Push the piston back in as far as it will
go, while being careful not to twist it.
(Note that some oil may overflow from
the reservoir tank at this time.)

Depress the brake lever as far as it will go, and then operate it several more times so
that the two pistons all move to their initial positions.
Remove the pad spacers, install the wheel, and then check that there is no interference
between the rotor and the caliper. If they are touching, adjust while referring to
"Installation of the caliper".
After checking the oil level, replace the reservoir tank cover.
