[. . . ] This includes service and maintenance practices as well as riding practices. Before each ride, always check your brakes for proper function and the brake pads for wear. [. . . ] Using a 5mm Allen wrench, turn the fixed inner pad adjuster counter clockwise 1/8 of a turn until there is a . 015"-. 020" (. 38-. 50mm) gap. Adjust the amount of lever travel by turning the adjuster barrel at your lever. Check that it spins freely and that the gaps, between the pad and the disc, are equal. If the gaps are unequal, or if there is drag, readjust the caliper position by loosening the mounting bolts and adjusting the caliper as needed. Hint: A white piece of paper can be used as a background to help sight down the disc looking for equal clearance between the pads and th disc. When the gaps are equal and wheel spins freely (without drag), torque the mounting bolts to 110 in-lbs (12. 43Nm). Step B-3 Torqueing Sequence Step C-2 Fork Adaptor Step C-7 Stringing Cable Starting Out Burnish: Disc brakes require a special burnishing period to achieve maximum braking power. The brake disc and pads should only be cleaned with isopropyl alcohol (not disc brake cleaner). Brake Pad Change : Due to wear, contamination, or damage, the brake pads will, on occasion have to be replaced. The following procedure is to be followed for that change of brake pads. Using a 5mm Allen wrench, turn the inner pad adjuster counter clock-wise until one engagement thread is exposed. To do this, pull the tab in the center of the pad backing plate toward the center of the caliper and out. Note: If you do not remove the outer pad first, you will not be able to remove the pads.
