Hydraulic disc brake

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.

• 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.

• Cut the brake hose so that the cut end is perpendicular to the length of the hose. If the brake hose is cut at an angle, fluid leaks may result.
