WARNING
For installation, adjustment and replacement information about products not found in the user's manual, consult the place of purchase or a distributor. A dealer's manual for professional and experienced bicycle mechanics is available on our website (https://si.shimano.com).
For safety, be sure to carefully read this "user's manual" before use, follow it for correct use, and save it so that you can refer back to it at any time.
The following instructions should always be followed in order to prevent personal injury, physical damage to equipment and the surroundings. The instructions are classified according to the degree of danger or damage that may occur if the product is used incorrectly.
DANGER - Failure to follow the instructions will result in death or serious injury.
WARNING - Failure to follow the instructions could result in death or serious injury.
CAUTION - Failure to follow the instructions could result in personal injury or physical damage to equipment and surroundings.

WARNING
- Because each bicycle may handle a little differently depending on the model, 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, which could lead to a serious injury due to a fall or collision.
- Do not disassemble or modify the product. This may cause the product to not operate correctly, and you may fall unexpectedly and be seriously injured.
- Before riding the bicycle, riders must become accustomed to the higher performance of this brake. 220 mm, 203 mm, and 180 mm disc brake rotors provide greater braking force than 160 mm disc brake rotors. If you ride the bicycle without becoming thoroughly familiar with the braking characteristics, braking may result in a fall from the bicycle, possibly resulting in serious injury or a fatal accident.
- Keep your fingers well away from the rotating disc brake rotors. The disc brake rotor is sharp enough to cause severe injury to your fingers if your fingers get caught in the openings of a moving rotor.
- Do not touch the calipers or disc brake rotor during or immediately after riding the bicycle. The calipers and disc brake rotor become hot during braking, so you may be burned if you touch them.
- Do not allow any oil or grease to get onto the disc brake rotor and brake pads. If the bicycle is ridden with oil or grease on the disc brake rotor and brake pads, the brakes may not work, and this could lead to a serious injury due to a fall or collision.
- Check the brake pad thickness and do not use them if they are 0.5 mm or less in thickness. Doing so may cause the brakes to not work, and this could lead to a serious injury caused by a fall or collision.
- Do not use the disc brake rotor if it is cracked or deformed. The disc brake rotor may break, and this could lead to a serious injury caused by a fall.
- Do not use the disc brake rotor if its thickness is 1.5 mm or less. Also, do not use it if the aluminum surface is visible. The disc brake rotor may break, and this could lead to a serious injury caused by a fall.
- Do not apply the brakes continuously. This may cause a sudden increase in brake lever stroke, causing the brakes to not work, and this could lead to a serious injury due to a fall or collision.
- Do not use the brakes if there is any fluid leakage. This may cause the brakes to not work, and this could lead to a serious injury caused by a fall or collision.
- Do not apply the front brake too strongly. If you do so, the front wheel may lock and the bicycle may topple forward, and this may cause a serious injury.
- Because the required braking distance will be longer during wet weather, reduce your speed. Apply the brakes early and gently. You may fall or collide and be seriously injured.
- A wet road surface can cause the tires to lose traction. To avoid this, reduce your speed and apply the brakes early and gently. If the tires lose traction, you may fall and be seriously injured.
- For use with the hydraulic disc brake type with dual control lever
- This hydraulic brake system has different braking characteristics than those of the rim brake type, indicating a relatively large braking force at the start of braking (higher than with the rim brake type); before use, become thoroughly familiar with the braking characteristics. If you ride the bicycle without becoming thoroughly familiar with the braking characteristics, braking may result in a fall from the bicycle, possibly resulting in serious injury or a fatal accident.
- The braking force of the hydraulic brake system will increase along with the size of the disc brake rotor (140 mm, 160 mm, 180 mm, 203 mm).
- Do not use a 203 mm disc brake rotor. This will excessively increase the braking force, which may cause you to lose control of the bicycle, fall, and be seriously injured.
- Only use a 180 mm disc brake rotor if you cannot obtain sufficient braking force with a 160 mm disc brake rotor during a test ride, such as when riding an e-road bike or if the rider is heavy. Otherwise, you may lose control of the bicycle, fall, and be seriously injured.
- If you feel that the braking force is too strong or too weak, stop using it and consult the place of purchase or a distributor. Accidents or falls may occur due to loss of control of the bicycle, which may result in serious injury.

CAUTION
- Precautions regarding SHIMANO genuine mineral oil
- If it gets in your eyes, flush your eye with clean water and seek immediate medical attention. Contact with the eyes may cause irritation.
- If it gets on your skin, wash it thoroughly with soapy water. Contact with the skin may cause rashes and difficulties.
- Protect your nose and mouth with a protective breathing mask and use in a well-ventilated room. Inhaling mineral oil vapor or fumes may cause nausea.
- If you inhale mineral oil vapor or fumes, immediately move to a place where there is fresh air. Cover yourself with a blanket. Stay warm in a stable position and seek professional medical assistance.
-Warm-up period
- Disc brakes have a certain warm-up period, and the braking force gradually increases along with the increasing warm-up period. Accidents or falls may occur due to loss of control of the bicycle, which may result in serious injury. The same situation occurs when replacing brake pads or the disc brake rotor.
