User manual SHIMANO SI-8E80A TECHNICAL INSTRUCTIONS

[. . . ] 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. · Check the brake cable for rust and fraying, and replace the cable immediately if any such problems are found. If this is not done, the brakes may not work correctly. [. . . ] · The R505 disc brakes are designed for optimum performance when used in combination with the BR-R505 (calipers), BL-R770/ST-6600 (brake lever), SM-RT61, SM-RT62 (rotor) and Shimano pad unit (M06). Use 2. 5 finger levers for canti brakes such as the BL-R770 or STI levers such as the ST-6600 for road bikes as the brake levers. Do not use in combination with V-BRAKE brake levers. If used in combination with V-BRAKE brake levers, it will not be possible to obtain sufficient braking force. If using in combination with 4-finger levers such as the BL-T400/ST-T400, the braking force will be higher. Accordingly, under some conditions such as certain riding positions or overall weight, the bicycle may fall over and injury may result if proper care is not taken. · Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or damaged parts may cause the bicycle to fall over and serious injury may occur as a result. 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. Installation Wheel spoke lacing Check that the spokes have been laced as shown in the illustration. Lace the spokes as shown in Figure 1 below for the left side of the front wheel (the side where the rotor is installed), and the left and right sides of the rear wheel, and as shown in Figure 2 below for the right side of the front wheel. Rotating direction of wheel Front left Rear left Rear right Front right Installing the calipers 1. Loosen the caliper fixing bolts, and then install the calipers to the frame so that the calipers work at the left and right. Caliper clamp bolt Secure the three bolts with a cap as shown in the illustration in order to prevent the bolts from coming loose. For post type < Front > < Rear > Caps Caps Caliper fixing bolts 2. While wearing protective gloves, apply pressure to the adapter in the counterclockwise direction while tightening the caliper clamp bolt. Fig. 2 Caliper clamp bolt Adjusting when the pads are worn Use a 3 mm Allen key to tighten the pad adjustment screw on the calipers so that clearances (A) and (B) are both 0. 2 ­ 0. 4 mm. Pad adjusting screw Installation of the rotor <SM-RT61> Install the rotor and the rotor tightening plate to the hub, and then install and tighten the bolts as shown in Fig. 1 Tightening plate Rotor B A While wearing gloves, apply a force to the rotor to turn it in a clockwise direction as shown in Fig. While doing this, tighten the rotor fixing bolts in the order shown in the illustration. Use a flat-tipped screwdriver or similar tool to bend the edges of the tightening plate over the heads of the bolts as shown in Fig. 2 Hub Rotor fixing bolts (#T25 torx) Adapter Tightening torque: 6 - 8 N·m {53 - 69 in. lbs. } (0. 2 ­ 0. 4 mm) B A (0. 2 ­ 0. 4 mm) Tightening torque: 2 - 4 N·m {18 - 35 in. [. . . ] lbs. } Tightening torque: 2 - 4 N·m {18 - 35 in. Depress the brake lever about 10 times until it touches the grip, and check that there are no problems with any components, and also that the rotors and the pads do not interfere with each other when the wheel is rotated. Tighten the pad adjusting screw so that the clearance between the brake pad and the rotor is 0. 2 ­ 0. 4 mm. Technical Service Instructions SI-8E80A-002 <ST-6600 / ST-5600> Secure the assembly with the installation nut on the outside of the bracket. Pull the bracket cover back and use a 5 mm Allen key to tighten the bolt. Tightening torque: 6 - 8 N·m {53 - 69 in. After checking that the brake pad and the rotor are not touching each other, check that there are no problems when the brake lever is depressed. [. . . ]
