[. . . ] · 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. 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. [. . . ] 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. · Read these Technical Service Instructions carefully, and keep them in a safe place for later reference. 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. I Installation of the hose Refer to the Service Instructions for the SM-BH59 brake hose (SI-8H20) for details on installing the hose. Make sure that the calipers and levers are in the positions shown in the illustrations. < For left lever > If the lever isn't stiff, adjust by the following procedure. Either a cap method or a wire ring method can be used to stop the bolts from turning. Use whichever method is suitable for the front fork and frame. Cap method < Front > Post type Caps Caps < Rear > When the lever is depressed once more, bubbles will rise up and be released into the reservoir tank. It can be useful to shake the hose gently or shift the position of the calipers at this time. Caps 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. Remove the wheel from the frame, and remove the brake pads as shown in the illustration. Tool 2. Set the brake lever so that it is parallel to the ground, and then remove the reservoir tank cover. Split pin 2. Set a 7mm socket wrench in place, attach a bag to the tube, and then place the tube onto the bleed nipple as shown in the illustration. Bleed nipple I Installation of the calipers (BR-S500) and securing the hose · Remove the pad spacer A (yellow), and then set the wheel which has the rotor onto the frame. 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. ) Piston 3. Loosen the bleed nipple by 1/8th of a turn to open it, and then pour oil into I 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 the reservoir tank. Gently operate the brake lever while doing this to help prime the system with the oil. Pad spacer A (yellow) Split pin 5. Install the new brake pads, and then install the pad spacers B (red). Depress the brake lever several times to check that the operation becomes stiff. 4. When the oil goes into the hose, the oil level in the reservoir tank will drop, so be sure to continue adding oil to maintain the oil level so that air is not drawn in through the port. [. . . ] Check that the rotor and the brake pads do not touch each other, and then check the oil level (adding more oil if required). After doing this, replace the reservoir tank cover. Split pin Pad spacer B (red) 1. Loosen the caliper fixing bolts so that the caliper can move sideways, and then install the adapter to the frame. 2. Depress the brake lever so that the rotor is being clamped by the pads, and then tighten the caliper fixing bolts. G International standard mounting type < Front > Fig. [. . . ]
