Mounting the adapter Installation Steps : (1) Before installing the calipers, ensure each wheel axle is correctly seated in the dropouts. (The brake rotor should be on the caliper mounting side) (2) Select the correct adapter (front or rear) for the size of rotor. If your frame and/or fork utilizes IS disc, brake mounts you will need the included IS-to-post mount caliper adapter. (3) Holding the adapter, with the engraved "F" facing toward you (away from the rotor and wheel), position it behind the frame/fork mounting holes. Bolt the adapter in this position to the frame/fork mounts. Now the engraved "F" should not be visible behind the mounts. Tighten the bolts to a final tightening torque of 6-8Nm. (4) Make sure the pads are correctly positioned in the caliper. Aftach the caliper to the adapter using the supplied Allen bolts. Do not fighten the bolts at this stage. (5) With the caliper mounting bolts still loose, depress the brake lever. The caliper will correctly center itself to the rotor. Keeping the brake lever depressed, tighten the caliper mounting bolts. Final fightening torque: 6-8Nm. Note: It's essential that you ensure the brake has the correct mounting system for your frame and fork. The measurement of disc brake mounts is based on the distance in millimeters between the the center of the two bolt mounting holes.
