5. Insert the correct brake pads and set the pad spacers (Figure 11.6, and see Table 6
below). There should be 2 mm between each pad and the rim when the brake is not
engaged
Make sure the pad carriers are oriented correctly so that the pads do no slide out when
the brake is applied.

6. Align the brake pads (Figure 11.7). Tighten the pad carrier nuts to 6-8 Nm.
7. With the left and right centering screws, center the brake.
To make the brake easier to adjust after the crankset is installed, the centering screws
are both accessed from the non-drive side of the bike (Figure 10.8).

8. Size and cut the cable (Figure 11.9).
Finish the end of the cable so that it will not interfere with the brake return spring.
If you choose to only cut the cable and not dress the end, the extended tunnel of the
wedge prevents immediate fraying of the cable.
If desired, solder the end. Or install a cable crimp, then bend it downward.
