TO ENSURE SAFETY
TO ENSURE SAFETY
WARNING
•
Be sure to follow the instructions provided in the manuals when installing the product.
It is recommended to use genuine Shimano parts only. If parts such as bolts and nuts become loose or damaged, the bicycle may suddenly fall over,
which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may cause serious injury.
•
Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.
•
After reading the dealer's manual thoroughly, keep it in a safe place for later reference.
Be sure to also inform users of the following:
•
The 203mm and 180mm disc brake rotors provide a higher braking force than the 160mm disc brake rotors. Make sure that you completely understand
the braking characteristics before using the brakes.
•
Each bicycle may handle slightly differently depending on the model.
Therefore, be sure to learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation of your
bicycle. Improper use of your bicycle's brake system may result in a loss of control or a fall, which could lead to severe injury. For proper operation,
consult a professional bicycle dealer or the bicycle's owner's manual. It is also important to practice riding and braking, etc.
•
Please make sure to keep your fingers away from the rotating disc brake rotor. The disc brake rotor is sharp enough to
inflict severe injury to your fingers if caught in the openings of the disc brake rotor while it is moving.
•
The calipers and disc brake rotor will become hot when the brakes are operated; do not touch them while riding or immediately after dismounting
from the bicycle. Otherwise you may get burned.
•
Be careful not to allow any oil or grease to get onto the disc brake rotor and brake pads. Otherwise the brakes may not work correctly.
•
If any oil or grease does get on the brake pads, you should consult a dealer or an agency. Otherwise the brakes may not work correctly.
•
If noise occurs during brake operation, the brake pads may have been worn down to the usable limit. Check that brake
system temperature has cooled down sufficiently, check the thickness of the brake pad. If the thickness is 0.5mm or
less, the brake pad needs to be replaced with a new one. Consult a dealer or an agency.
•
If the disc brake rotor is cracked or deformed, immediately stop using the brakes and consult a dealer or an agency.
•
If the disc brake rotor becomes worn down to a thickness of 1.5mm or less, or if the aluminum surface appears, immediately stop using the brakes and
consult a dealer or an agency. The disc brake rotor may break, and you may fall off the bicycle.
•
Vapor lock may occur if the brakes are applied continuously. To solve this problem, momentarily release the lever.
Vapor lock occurs when the oil inside the brake system becomes heated, which causes the water or air bubbles inside the brake system to expand.
This can then result in a sudden increase in the brake lever stroke.

TO ENSURE SAFETY
•
The disc brake is not designed to work when the bicycle is upside down. If the bicycle is turned upside down or on its side, the brake may not work
correctly, and a serious accident could occur. Before riding the bicycle, be sure to operate the brake lever a few times to check that the brakes operate
normally. If the brakes do not operate normally, stop using the brakes and consult a dealer or an agency.
•
If you feel no resistance when depressing the brake lever, immediately stop using the brakes and consult a dealer or an agency.
•
If fluid leaks occur, immediately stop using the brakes and consult a dealer or an agency.
•
If the front brake is applied too strongly, the wheel may lock and the bicycle may fall forward, and serious injury may result.
•
Always make sure that the front and rear brakes are working correctly before riding the bicycle.
•
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. Reduce your speed and apply the brakes early and
gently.
•
The lever should never be altered. Otherwise, the lever may break preventing braking operation.
•
Check before riding that there is no damage such as cracking. If there is any damage, stop using the bicycle and consult a dealer or an agency.
Otherwise, the lever may break preventing braking operation.
For Installation to the Bicycle, and Maintenance:
•
Please make sure to keep your fingers away from the rotating disc brake rotor during installation or maintenance of
the wheel. The disc brake rotor is sharp enough to inflict severe injury to your fingers if caught in the openings of the
disc brake rotor while it is moving.
•
If the disc brake rotor is worn, cracked or warped, it should be replaced.
•
If the disc brake rotor becomes worn down to a thickness of 1.5mm or the aluminum surface becomes visible, be sure to replace the disc brake rotor
with a new one.
•
Check that the brake components have cooled down sufficiently before attempting to adjust the brakes.
•
Use only Shimano genuine mineral oil. If other types of oil are used, it may cause problems with brake operation, and cause the system to be unusable.
•
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 or reused 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.
•
If cutting the brake hose in order to adjust the length of the hose, or when changing over the brake hose from left to right or vice versa, be sure to
bleed the air from the hose according to steps given in “Adding Shimano genuine mineral oil and bleeding air”.
•
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 bleed screw is closed, or which accumulate in various parts of the brake system when it is used for long periods. This disc brake system is not
designed to work with the bicycle 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 danger that the brakes may not operate and a serious accident may
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 according to the following procedure.
If brake does not seem to work (feels 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 are still sluggish, bleed the air from the brake system. (Refer to “Adding the Shimano genuine mineral oil and bleeding air”.)

TO ENSURE SAFETY
•
If the quick release lever on the hub is on the same side as the disc brake rotor, they may interfere with each other, which is dangerous, so check that
they do not.
•
Shimano disc brake systems are not compatible with tandem bicycles. Because tandem bicycles are heavier, the stress on the brake system increases
during brake operation. If hydraulic disc brakes are used with tandem bicycles, the oil temperature will become too high and vapor locks or ruptures
in the brake hoses may occur, causing the brakes to fail.
SM-RTAD05 Disc brake rotor adapter
•
Disc brake rotors with diameters of up to Ø203mm can be installed. If disc brake rotors with a larger diameter than this are installed, the braking force
may damage the main unit.
Brake hose
•
After installing the brake hose to the brake unit, adding Shimano genuine mineral oil and bleeding air bubbles, depress the lever again several times
to check that the brakes are operating normally and there are no fluid leaks from the hose or the system.
•
The connector insert is for this brake hose only. Use an appropriate connector insert according to the following table. Use of a connector insert
incompatible with the brake hose may cause fluid leaks.
Model No. Length Color
SM-BH90 11.2mm Silver
SM-BH59/80 13.2mm Gold
YM-BH81 13.2mm Silver
•
Do not reuse the olive piece or the connector insert when reinstalling. A damaged or reused olive, or connector insert, may not provide a secure brake
hose connection, possibly causing the brake hose to disconnect from the calipers or brake lever.
If the brake hose becomes disconnected, there is danger that the brakes may suddenly stop working.

TO ENSURE SAFETY
CAUTION
Be sure to also inform users of the following:
Cautions on Shimano genuine mineral oil
•
Contact with eyes may result in irritation. In the event of contact with eye, wash with water and seek medical attention immediately.
•
Contact with skin may cause a rash and discomfort. In the event of contact with skin, wash well with soap and water.
•
Inhalation of Shimano genuine mineral oil mist or vapors may cause nausea. Cover nose and mouth with a respirator type mask and use in a well
ventilated area. If Shimano genuine mineral oil mist or vapor is inhaled, cover up with a blanket and go immediately to an area with fresh air. Stay
warm and calm, and seek professional medical advice.
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 disc brake rotor
are replaced.
For Installation to the Bicycle, and Maintenance:
•
When using the Shimano original tool (TL-FC36) to remove and install the disc brake rotor fixing ring, be careful not to touch the outside of the disc
brake rotor with your hands. Wear gloves to protect your hands from getting cut.
Handling Shimano genuine mineral oil
•
Contact with eyes may result in irritation. Use safety glasses when handling, and avoid contact with eyes.
In the event of contact with eye, wash with water and seek medical attention immediately.
•
Contact with skin may cause a rash and discomfort. Use gloves when handling.
In the event of contact with skin, wash well with soap and water.
•
Do not drink. May cause vomiting or diarrhea.
•
Keep out of reach of children.
•
Do not cut, let near 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 caution when preparing the 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. Keep from heat or flame, Petroleum Class III, Danger level III
When cleaning with a compressor
•

TO ENSURE SAFETY
NOTE
Be sure to also inform users of the following:
•
When the bicycle wheel has been removed, it is recommended that pad spacers are installed. Do not depress the brake lever while the wheel is
removed. If the brake lever is depressed without the pad spacers installed, the pistons will protrude further than normal. If that happens, consult a
dealer.
•
Use soapy water and a dry cloth when cleaning and carrying out maintenance of the brake system. Do not use commercially available brake cleansers
or silencing agents. Such substances can cause damage to parts such as seals.
•
In the case of carbon levers, wash them with a soft cloth using a neutral detergent. Otherwise, the material may break down and be damaged.
•
Avoid leaving the carbon levers in areas of high temperature. Also keep them well away from fire.
•
Products are not guaranteed against natural wear and deterioration from normal use and aging.
•
For maximum performance we highly recommend Shimano lubricants and maintenance products.
For Installation to the Bicycle, and Maintenance:
•
The 203mm and 180mm disc brake rotors have a larger diameter than the 160mm disc brake rotors for cross-country bicycles, and so the flexing of
these disc brake rotors is greater. As a result, they will interfere with the brake pads.
•
If the brake caliper mounting boss and the fork end are not parallel, the disc brake rotor and caliper may touch.
•
When the bicycle wheel has been removed, it is recommended that pad spacers are 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-shaped 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, use a flat-shaped tool to 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 bleed screws 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 cleaning and carrying out maintenance of the brake system. Do not use commercially available
brake cleansers or silencing agents. Such substances can cause damage to parts such as seals.
•
Do not remove the pistons when disassembling the calipers.
•
If the disc brake rotor is worn, cracked or warped, it should be replaced.
SM-RTAD05 Disc brake rotor adapter
•
When using this disc brake rotor adapter to install disc brake rotors, the structure of the adapter means that there will be more play than normal in
the disc brake rotor. Because of this, the disc brake rotor may interfere with the brake pads. Furthermore, it may also interfere with the calipers in the
radial direction (upward).
•
This product cannot be used with the 6-bolt disc brake rotor that is installed with an aluminum adapter (SM-RT86/RT76).
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using
the product.
